SCORE research domain is cooperative, distributed, and Process-Aware Web Information Systems. The advent of the web 2.0 and its emphasis on services pushed new IS applications such as electronic commerce, collaborative editing, e-learning, e-engineering to become widespread. A common characteristic of these applications is that they are cooperative, human-centered, creative by nature but also driven by sophisticated underlying infrastructure. Such applications are also distributed in space (people work in different locations), in time (people work at different time) and they cross organizational barriers, making difficult their coordination and crucial the issues of privacy and trust. In this domain, the evolution of the Internet and of the Web seems to open new challenges and questions every day. In our case, we have chosen to consider two dimensions of the issues faced by users and developers of web and service based systems :
The first dimension refers to management of collaborative data, a key aspect in the development of distributed collaborative systems.
The second dimension is concerned with assembling and coordinating high level services, involving people, applications, and information sources on the basis of process models. This is part of the service oriented computing research field.
We are considering these two dimensions at a Web scale where there is no central authority that governs the system. This raises many challenges related to governance, compliance and security, trust and privacy but also to awareness and coordination. At this scale, we are also always facing the recurring problem of interoperability as we want to offer collaborators a flexibility concerning the chosen work models and technologies. We are tackling these two dimensions in specific domains where they have strong interrelations:
in software engineering where it is always difficult to find the best compromise between explicit and implicit coordination and where stands the difficulties related to collaborative software writing.
in crisis management where many organisations have to cooperate in a very ad hoc way, share data and coordinate with a constantly changing goal, with very big issues at stake and with strong political emphasis.
and in all domains where there is a strong need for cooperation;

Our scientific foundations are grounded on two different dimensions, distributed collaborative systems supported by sophisticated data sharing mechanisms and service oriented computing with an emphasis on orchestration and on non functional properties.
Distributed collaborative systems enable distributed group work using computer technologies. Designing such systems require an expertise in the domain of Distributed Systems (DS) and in the Computer-supported collaborative work (CSCW) research area. Besides theoretical and technical aspects of distributed systems, design of distributed collaborative systems must take into account the human factor to offer solutions suitable for users and groups. SCORE team vision is to move away from a centralized authority based collaboration towards a decentralized collaboration where users have full control over their data that they can store locally and can decide with whom to share them. In this type of collaboration SCORE team investigated the issues of management of distributed shared data and coordination between users and groups.
Service oriented Computing is an established domain in which the ECOO and now the SCORE team has been working on for a long time. It refers to the general discipline that studies the development of computer applications at the scale of the web. In this context, a service is an independent software program with a specific functional context and capabilities published as a service contract (or more traditionally an API). Service composition is the aggregation of a set of services whose interactions are coordinated. The scale, the autonomy of services, the heterogeneity and some well defined design principles underlying SoC opens new research questions that are at the basis of the SCORE problematic and that spans the disciplines of distributed computing, software engineering and CSCW. Our approach to contribute to the general vision of Service Oriented Computing and more generally to the emerging discipline of Service Science has been and is still to focus on the question of the efficient and flexible construction of reliable and secure high level services through the coordination/orchestration/composition of other services provided by distributed organizations or people.
Collaborative systems are distributed systems that allow users to share data. One important issue is to manage consistency of shared data according to concurrent access. Traditional consistency criteria such as locking, serializability, linearizability are not adequate for collaborative systems.
Causality, Convergence and Intention preservation (CCI) are more suitable for developing middleware for collaborative applications.
We develop algorithms for ensuring CCI properties on collaborative distributed systems. Constraints on the algorithms are different according to the type of distributed system and type of data. The distributed system can be centralized, decentralized or peer-to-peer. The type of data can include strings, growable arrays, ordered trees, semantic graphs and multimedia data.
Replication of data among different nodes of a network allows improving reliability, fault-tolerance, and availability. When data are mutable, consistency among the different replicas must be ensured. Pessimistic replication is based on the principle of single-copy consistency while optimistic replication allows the replicas to diverge during a short time period. The consistency model for optimistic replication is called eventual consistency, meaning that replicas are guaranteed to converge to the same value when the system is idle.
Our research focuses on the two most promising families of optimistic replication algorithms for ensuring CCI:
the algorithms based on commutative replicated data types (CRDT)
Operational transformation algorithms are based on the application of a transformation function when a remote modification is integrated into the local document. Integration algorithms are generic, being parameterized by operational transformation functions which depend on replicated document types. The advantage of these algorithms is their genericity. These algorithms can be applied to any data type and they can merge heterogeneous data in a uniform manner.
Commutative replicated data types is a new class of algorithms initiated by woot . They ensure consistency of highly dynamic content on peer-to-peer networks. Unlike traditional optimistic replication algorithms, they can ensure consistency without concurrency control. CRDT algorithms rely on natively commutative operations defined on abstract data types such as lists or ordered trees. Thus, they do not require a merge algorithm or an integration procedure.
Business Process Management (BPM) is considered as a core discipline behind Service Management and Computing. BPM, that includes the analysis, the modeling, the execution, the monitoring and the continuous improvement of enterprise processes is for us a central domain of studies.
A lot of efforts has been devoted in the past years to established standards business process models founded on well grounded theories (e.g. Petri Nets) that meet the needs of both business analyst but also of software engineers and software integrators. This has lead to heated debate as both points of view are very difficult to reconciliate between the analyst side and the IT side. On one side, the business people in general require models that are easy to use and understand and that can be quickly adapted to exceptional situations. On the other side, IT people need models with an operational semantic in order to be able transform them into executable artifacts. Part of our work has been an attempt to reconcile these point of views, leading on one side to the Bonita product and more recently on our work in crisis management where the same people are designing, executing and monitoring the process as it executes. But more generally, and at a larger scale, we have been considering the problem of process spanning the barriers of organisations. This leads us to consider the more general problem of service composition as a way to coordinate inter organisational construction of application providing value based on the composition of lower level services .
More and more, we are considering processes as piece of software whose execution traverse the boundaries of organisations. This is especially true with service oriented computing where processes compose services produced by many organisations. We tackle this problem from very different perspectives, trying to find the best compromise between the need for privacy of internal processes from organisations and the necessity to publicize large part of them, proposing to distribute the execution and the orchestration of processes among the organisations themselves, and attempting to ensure transactional properties in this distributed setting .
Non functional aspects of service composition relate to all the properties and service agreements that one want to ensure and that are orthogonal to the actual business but that are important when a service is selected and integrated in a composition. This includes transactional context, security, privacy, and quality of service in general. Defining and orchestrating services on a large scale while providing the stakeholders with some strong guarantees on their execution is a first class problem for us. For a long time, we have proposed models and solutions to ensure that some properties (e.g. transactional properties) were guaranteed on process execution, either through design or through the definition of some protocols. Our work has also been extended to the problems of security, privacy and service level agreement among partners. These questions are still central in our work.
E-government is now a well established domain that provides its own requirements in the field of service and information management. From our perspective, mostly processes, e-government applications have very strong requirements regarding security, privacy and interoperability between different organizations, belonging potentially to different countries. One of the prominent contributions we have made in this domain is related to our collaboration with SAP on the relationship between processes, security policies and the problem of delegation that we considered as a important for organizational flexibility. This work resonnate also with its current continuation in crisis management.
Crisis management is a special case of e-government application as it involves mostly governmental agencies in coordination with other organizations like the Red Cross or other NGO. Moreover, it brings with it a lot of requirements that are very interesting for us in the domain of coordination: a crisis process shall be very flexible, adaptable and distributed. It is mostly human driven and can be critical. In this domain, we are collaborating with SAP to define a new model of coordination that should support people involved in crisis resolution.
Collaborative knowledge building process is a distributed social process . During this process, Knowledge is built by a constellation of communities, each community being a node in the knowledge building network. Each node in the network is autonomous and has its own knowledge that can be exchanged and negotiate with other communities. A peer-to-peer architecture is more compatible with social architecture of knowledge building processes . In addition, knowledge is basically created by individuals involved in social process . Therefore, it is fundamental to support personal knowledge building in a collaborative knowledge building environment.
We develop distributed semantic wikis for collaborative knowledge building. These environments support the distributed social process of knowledge building and support personal knowledge building.
Software engineering can be seen as distributed collaborative systems. Software Forges are social software. They transform stranger into collaborators, sometimes into developers. Forges are online services that allow instantiating, composing and managing collaborative services. Traditionally, provided collaborative services are version control systems, issue trackers, forums, mailing lists or wikis. We are applying our research results on coordination and data sharing into this context.
The QualiPSo Factory
Processes have received a lot of attention in the last decade and proposed workflow solutions for office automation. The topic is subject today to a lot of interests carried by the expansion of business on the Web. However it is required need to satisfy new application requirements and execution contexts. We are interested in different aspects of process engineering: the management of change in business process; modeling and implementing Quality of Services properties (time, security, constraints...); composing existing process fragments of different nature and models; decentralizing a global process for a distributed execution with organizational constraints; process governance. Most of these aspects are considered within the frame of Web services and/or peer to peer architectures, and we are also interested in proposing new models of process for new applications domains.
Globalization and the increase of competitive pressures created the need for agility in business processes, including the ability to outsource, offshore, or otherwise distribute its once-centralized business processes or parts thereof. While hampered thus far by limited infrastructure capabilities, the increase in bandwidth and connectivity and decrease in communication cost have removed these limits. An organization that aims for such fragmentation of its business processes needs to be able to separate the process into different parts. Therefore, there is a growing need for the ability to fragment one's business processes in an agile manner, and be able to distribute and wire these fragments so that their combined execution recreates the function of the original process. Additionally, this needs to be done in a networked environment, which is where Service Oriented Architecture plays a vital role.
Our work is focused on solving some of the core challenges resulting from the need to dynamically restructure enterprise interactions. Restructuring such interactions corresponds to the fragmentation of intra and inter enterprise business process models. It describes how to identify, create, and execute process fragments without loosing the operational semantics of the original process models. It also proposes methods to optimize the fragmentation process in terms of QoS properties and communication overhead , . Moreover, it presents a framework to model web service choreographies in Event Calculus formal language.
Walid Fdhila has successfully defended his thesis on October, 7th .
Web services composition and monitoring are still highly active and widely studied research directions. Little work however has been done in integrating these two dimensions using an unified framework and formalism. Classical approaches introduce an additional layer for handling the composition monitoring and thus do not provide the important execution time violations feedback to the composition process. This year, we proposed the DISC framework which aims to provide a highly declarative event-oriented model to accommodate various aspects such as composition design and exceptions, data relationships and constraints, business calculations and decisions, compliance regulations, security or temporal requirements. Then, the same model is used for combining the control of the composition definition, its execution and the composition monitoring. We proposed a service oriented architecture with a flexible logic, including complex event patterns and choreographies, business oriented rules, and dynamic control of compositions. Advantages of this unified framework are the higher level of abstraction to design, execute, and reason upon a composition, the flexibility of the approach, and the ability to easily include non-functional requirements such as temporal or security issues and we implement the DISC framework using the Discrete Event Calculus reasoner. Ehtesham Zahoor defended his thesis in November , and had presented the DISC framework at ICWS 2011 .
We also continued the previous work initiated within the Associate Team INRIA VanaWeb about the provisioning of Web services composition using constraints solvers. The approach consists in instantiating this abstract representation of a composite Web service by selecting the most appropriate concrete Web services. This instantiation is based on constraint programming techniques which allow matching Web services according to a given request. The proposal performs this instantiation in a distributed manner, i.e., the solvers for each service type are solving some constraints at one level, and they are forwarding the rest of the request (modified by the local solution) to the next services. When a service cannot provision part of the composition, a distributed backtrack mechanism enables to change previous solutions (i.e., provisions). A major interest of this approach is to preserve privacy: solutions are not sent to the whole composition, services know only the services to which they are connected, and parts of the request that are already solved are removed from the next requests.
In the continuation of work done previously on change management during process execution, we are conducting work on the governance of change at the business level and on its implications at the architecture and infrastructure level of an information system. Last year was devoted to the definition of the transformation rules that allowed to go from a business model to an IT model, i.e. a transformation between model based on different paradigms. During this year, a great deal of effort has been done in order to extend our work on Business to IT alignment management. Our goal is still to maintain this alignment at the lowest possible cost when the business process are changing . Further than that we are trying to describe and validated an engineering method to help designer to maintain this alignment .
Distributed processes governance is a very important challenge. In the past, we proposed various approaches for dealing with distribution, particularly for computing a set of sub-processes that can be distributed and that are equivalent to a given process. However, we did not deal with non-functional requirements as the focus was only on control and data flows. In this work, we try to deal not only with functional requirements, but also with non-functional requirements, in particular the security aspects. With Aymen Baouab, we already proposed an event-based approach that is able to verify that choreographies are valid with respect to given constraints (security constraints for instance) .
As said before, crisis management has been a very fruitfull domain to investigate new approaches in the domain of high value, human driven activity coordination in a multi organisational setting. Our work benefits from a large amount of use cases and detailed accounts of previous dramatic events to analyze requirements and confront our proposals. 2011 has been devoted to terminate the evaluation and the validation of the model that we have defined during the previous years. It has also been devoted to complete the work done in the previous years on the inter organisational dimension of the coordination management . The entire contribution on crisis management, i.e. the model, the system and the evaluation are described in Joern Franke PhD document
In order to try to leverage this work in a more information system oriented way, we have started some collaboration to confront our view on coordination with existing reference model for humanitarian operations . We are currently looking for alternative financing vehicle in order to continue this work.
This work was conducted as a cooperation with SAP Research Sophia Antipolis and partially funded by a CIFRE Grant.
Starting with Web2.0 era, the web became easily writable and changeable, and nowadays, it is getting more real-time. Rather than requiring that users or their software check a source periodically for updates, real-time web is a paradigm based on the principle of pushing information to users as soon as it is available. We are faced with an explosion of real-time social software (Twitter, Facebook, etc.). Even if many social software are currently available, most of them rely on collaborative systems with a centralized architecture or authority and consequently suffer of intrinsic problems of centralization: lack of fault tolerance, poor scalability, costly infrastructure, problems of privacy.
Distributed collaborative systems (DCS) ease and coordinate collaboration among multiple users who jointly fulfill common tasks over computer networks without the need of a central architecture or authority .
We continued our work on migrating DCS to pure peer-to-peer architectures. This year we focussed on the real-time aspect of the collaboration. We evaluated replication mechanisms suitable for real-time collaboration over peer-to-peer architectures.
Moreover, peer-to-peer collaborative systems need revisiting traditional security models that prevent users from accessing to data and granted rights are checked before access is allowed. These access control mechanisms are too strict and they do not scale well in a peer-to-peer architecture. We make the assumption that an effective collaboration should rely on a flexible optimistic security model based on trust. This year we proposed a new collaboration model based on contracts where we rely on an optimistic security model. Rather than adopting an a priori strict enforcement of security rules, in this optimistic solution, access is given first to data without control but with restrictions that are verified a posteriori.
Nowadays, real-time collaborative editing systems such as Etherpad or Google Docs became very popular. The operational transformation (OT) approach is a traditional optimistic replication mechanism that was used for real-time collaboration. Recently, Commutative Replicated Data Types (CRDTs) were introduced as a new class of replication mechanisms whose concurrent operations are designed to be natively commutative. CRDTs, such as WOOT, Logoot, Treedoc, and RGAs, are expected to be substitutes of replication mechanisms in collaborative editing systems.
We investigated the suitability of CRDTs for realtime collaborative editing . To reflect the tendency of decentralized collaboration, which can resist censorship, tolerate failures, and let users have control over documents, we collect editing logs from real-time peer-to-peer collaborations. We provided a theoretical evaluation as well as an experimental one by replaying the editing logs on various CRDTs and OT algorithms implemented in the same environment. We found out that CRDT algorithms initially designed for peer-to-peer asynchronous collaboration are suitable for real-time collaboration. Moreover, they outperform some representative operational transformation approaches that were well established for real-time collaboration in terms of generation time, remote integration time and space complexity
In the push-pull-clone collaborative editing model widely used in distributed version control systems users replicate shared data, modify it and redistribute modified versions of this data without the need of a central authority. However, in this model no usage restriction mechanism is proposed to control what users can do with the data after it has been released to them. We extended the push-pull-clone model with contracts that express usage restrictions and that are checked a posteriori by users when they receive the modified data , . We proposed a merging algorithm that deals not only with modifications on data but also with contracts. A log-auditing protocol was used to detect users who do not respect contracts after they received data and to adjust user trust levels. The associated trust values can be computed by using any existing decentralised trust model. Our proposed contract-based model has been implemented and evaluated by using PeerSim simulator.
In the continuation of our previous work on semantic-based and model-based solutions for interoperability, we applied and experienced a variety of semantic annotation types (structural, terminological and behavioral) in the frame of dynamic web services discovery and for competence management systems. In addition, we explored semantic graphs as a formal framework for competence description and management. Further, in order to ease semantic interoperability of heterogeneous competence management systems, we are defining a generic representation model that could serve as a shared ontology for these types of systems.
Since several years, we are strengthening our relationships with SAP Research in the areas of process management and security. This collaboration has been formalized in 2008 by the funding of Joern Franke under a CIFRE contract to work on a PhD thesis on process models for crisis management (or crisis process managements systems). The PhD has been defended in october 2011.

Massive computing systems and their applications suffer from a fundamental tension between scalability and data consistency. Avoiding the synchronisation bottleneck requires highly skilled programmers, makes applications complex and brittle, and is error-prone.
The ConcoRDanT project (oct. 2010 – sep. 2013) will investigate a promising new approach that is simple, scales indefinitely, and provably ensures eventual consistency. A Commutative Replicated Data Type (CRDT) is a data type where all concurrent operations commute. If all replicas execute all operations, they converge; no complex concurrency control is required. We have shown in the past that CRDTs can replace existing techniques in a number of tasks where distributed users can update concurrently, such as co-operative editing, wikis, and version control. However CRDTs are not a universal solution and raise their own issues (e.g., growth of meta-data).
The ConcoRDanT project engages in a systematic and principled study of CRDTs, to discover their power and limitations, both theoretical and practical. Its outcome will be a body of knowledge about CRDTs and a library of CRDT designs, and applications using them. We are hopeful that significant distributed applications can be designed using CRDTs, a radical simplification of software, elegantly reconciling scalability and consistency.

The STREAMS project (nov. 2010 – oct. 2013) proposes to design peer-to-peer solutions that offer underlying services required by real-time social web applications and that eliminate the disadvantages of centralised architectures. These solutions are meant to replace a central authority-based collaboration with a distributed collaboration that offers support for decentralisation of services.
The STREAMS project aims to advance the state of the art on peer-to-peer networks for social and real-time applications. Scalability is generally considered as an inherent characteristic of peer-to-peer systems. It is traditionally achieved using replication technics. Unfortunately, the current state of the art in peer-to-peer networks does not address replication of continuously updated content due to real-time user changes. Moreover, there exists a tension between sharing data with friends in a social network deployed in an open peer-to-peer network and ensuring privacy. One of the most challenging issues in social applications is how to balance collaboration with access control to shared objects. Interaction is aimed at making shared objects available to all who need them, whereas access control seeks to ensure this availability only to users with proper authorisation. STREAMS project aims at providing theoretical solutions to these challenges as well as practical experimentations.
