Language oriented programming is an approach to software composition based on domain specific languages (DSL) dedicated to specific aspects of an application domain. In order to combine such languages we embed them into a host language (namely Haskell, a strongly typed higher-order lazy functional language). A DSL is then given by an algebraic type, whose operators are the constructors of abstract syntax trees. Such a multi-sorted signature is associated to a polynomial functor. An algebra for this functor tells us how to interpret the programs. Using Bekić's Theorem we define a modular decomposition of algebras that leads to a class of parametric multi-sorted signatures, associated with regular functors, allowing for the modular design of DSLs.

“…Indeed, although they are very often the main actors of collaboration, they are usually modelled as plain resources performing specific tasks in a context [3]. It is entirely appropriate that collaborative business process models explicitly highlight the roles played by users, as long as their implications would be predominant in collaboration: this is what Badouel et al propose in the GAG (Guarded Attribute Grammars) model [3,2], which is a grammatical approach to model collaborative, distributed, data-driven and user-centric business processes.…”

Guarded attribute grammars and publish/subscribe for implementing distributed collaborative business processes with high data availability

With the ever-increasing development of the Internet and the diversification of communication media, business processes of companies are increasingly collaborative and distributed. This contrasts with traditional solutions deployed for their management which are usually centralized, based on the activity flow or on the exchanged documents. Moreover, the users who are usually the main actors in collaborations are often relegated to second place. Recently, a distributed, data-driven and user-centric approach called Guarded Attributed Grammar (GAG) has been proposed for the modeling of such processes; it thus provides an answer to most of these limitations. In this paper, we present an approach for implementing business processes modeled using GAG in which communications are done by publish/subscribe with redirection of subscription (pub/sub-RS). The pub/sub-RS-which we propose-guarantees high data availability during the process execution by ensuring that an actor, perceived as a subscriber, will always receive a data he needs to perform a task as soon as it is produced. Moreover, if the data is semi-stuctured, and produced collaboratively and incrementally by several actors, its subscribers will be notified as soon as one of its components (a prefix) is produced simultaneously, as they will be subscribed in a transparent way to the remaining components (the suffix).RÉSUMÉ. Avec le développement toujours croissant de l'Internet et la diversification des moyens de communication, les processus métiers sont de plus en plus collaboratifs et distribués. Ceci contraste avec les solutions traditionnelles déployées pour leur gestion qui sont habituellement centralisées, basées sur le flux d'activités ou sur les documents échangés. Bien plus, les utilisateurs qui sont généralement les acteurs principaux dans la collaboration y sont souvent relégués au second rang. Récemment, une approche distribuée, centrée sur l'utilisateur et pilotée par les données appelée Grammaires Attribuées Gardées (GAG), a été proposée pour la modélisation de tels processus; elle fournit donc une réponse à la plupart de ces limitations. Dans ce papier, nous présentons une approche de mise en oeuvre de processus métiers modélisés à l'aide des GAG dans laquelle les communications se font par publish/subscribe avec redirection de souscriptions (pub/sub-RS). Le pub/sub-RS (que nous proposons) garantit une haute disponibilité des données pendant l'exécution d'un processus en assurant qu'un acteur (perçu comme un abonné) recevra toujours une donnée dont il a besoin pour effectuer une tâche dès qu'elle est produite. De plus, si la donnée est semi-structurée et produite collaborativement et incrémentalement par plusieurs acteurs, ses abonnés seront notifiés dès qu'une de ses composantes (un préfixe) est produite en même temps qu'ils seront abonnés de manière transparente aux composantes résiduelles (le suffixe).

Administrative workflows refer to variable business processes in which all cases are known; tasks are predictable and their sequencing rules are simple and clearly defined. When such processes are collaboratively executed by several actors, it may be desirable, for security reasons (confidentiality), that each of them has at all times, only a partial perception (this is what we call "actor's view") of the current process state. This concern seems sufficiently important to be considered when specifying such workflows. However, traditional workflow specification languages (BPMN, BPEL, YAWL) only partially address it. This is why we present in this paper, a new language for specifying administrative workflows that allows us not only to simply model all of the processes tasks and their sequence, but also and especially to explicitly express the rights of the various actors with respect to each of them, in order to guarantee a certain degree of security. The proposed model is an executable grammatical specification that allows to express using decorated productions, the different types of basic flows (sequential, parallel, alternative and iterative) that are found in workflow specification languages; moreover, it also allows to specify the rights of each actor in each process and on its data in a formalism similar to that used in UNIX-like operating systems.
