Monotonicity Types

In the face of the increasing trend in application development to interact with more and more remote services, and cognizant of the fact that issues arising from data consistency and task coordination are core challenges in distributed programming, the sys ...

Type Soundness Proofs with Definitional Interpreters

Tiark Rompf, Nada Amin

While type soundness proofs are taught in every graduate PL class, the gap between realistic languages and what is accessible to formal proofs is large. In the case of Scala, it has been shown that its formal model, the Dependent Object Types (DOT) calculu ...

Offer semantics: Achieving compositionality, flattening and full expressiveness for the glue operators in BIP

Simon Bliudze, Eduard Baranov

Based on a concise but comprehensive overview of some fundamental properties required from component-based frameworks, namely compositionality, incrementality, flattening, modularity and expressiveness, we review three modifications of the semantics of glu ...

RSP-QL Semantics: a Unifying Query Model to Explain Heterogeneity of RDF Stream Processing Systems

Jean Paul Calbimonte Perez

RDF and SPARQL are established standards for data interchange and querying on the Web. While they have been shown to be useful and applicable in many scenarios, they are not sufficiently adequate for dealing with streams of data and their intrinsic continu ...

Extended Connectors: Structuring Glue Operators in BIP

Simon Bliudze, Eduard Baranov

Based on a variation of the BIP operational semantics using the offer predicate introduced in our previous work, we extend the algebras used to model glue operators in BIP to encompass priorities. This extension uses the Algebra of Causal Interaction Trees ...

VISUAL CONTRACTS: A way to reason about states and cardinalities in IT system specifications

Alain Wegmann, Lam Son Lê, José Diego de la Cruz Garcia

Visual modeling languages propose specialized diagrams to represent behaviour and concepts necessary to specify IT systems. As a result, to understand a specification, the modeller needs to analyze these two types of diagrams and, often, additional stateme ...

A Method of Functional Alignment Verification in Hierarchical Enterprise Models

Alain Wegmann, Irina Rychkova

Enterprise modeling involves multiple domains of expertise: requirements engineering, business process modeling, IT development etc. Our experience has shown that hierarchical enterprise models, made of an assembly of system models, are effective. In these ...

Isolation-only Transactions by Typing and Versioning

In this paper we design a language and runtime support for isolation-only, multithreaded transactions (called tasks). Tasks allow isolation to be declared instead of having to be encoded using the low-level synchronization constructs. The key concept of ou ...
