iServe Description ================== iServe is what we refer to as service warehouse which unifies service publication, analysis, and discovery through the use of lightweight semantics as well as advanced discovery and analytic capabilities. iServe provides the typical features of service registries and additional functionality that exploits service descriptions, service annotations and further data gathered and derived from the analysis of these descriptions, data crawled from the Web, periodic monitoring and user activities. iServe builds upon lessons learnt from research and development on the Web and on service discovery algorithms to provide a generic semantic service registry able to support advanced discovery over both Web APIs and WSDL services described using heterogeneous formalisms. Accessing iServe ================ Applications and users can interact with iServe through a number of mechanisms: - Linked Data - RESTful API - HTML Front end Linked Data ----------- Once published in iServe, the service descriptions are exposed following Linked Data principles. In particular, each service description is given a unique and resolvable HTTP URI exposing service descriptions in both HTML and RDF through content negotiation. Additionally, the entire registry can be queried through a SPARQL endpoint. RESTful API ----------- Programmatic access to iServe's functionality is provided through a RESTful API. The API allows applications to create, read, update, and delete services, as well as it allows accessing the discovery algorithms implemented. Graphical User Interface ------------------------ iServe includes a Web-based user interface giving access to the content of the service registry and allowing users to search for them, etc Service Languages and Ontologies Supported ========================================== Support to different formalisms is provided through an extensible set of import plugins which transform these into the core conceptual model used by iServe. In particular iServe currently supports: - WSDL v1 and v2 - SAWSDL - OWL-S v1.1 - Web Service Contest's proprietary format - MicroWSMO - WSMO-Lite - Swagger Spec up to v1.2 Discovery Algorithms Implemented ================================ iServe provides an extensible plugin-based discovery engine which allows one to introduce new algorithms easily and combine them with existing ones on the fly. Discovery results are exposed using diverse serialisation formats (e.g., ATOM, JSON) and can be combined through simple set operations like Union, Intersection, and Subtraction. Currently iServe provides the following discovery plugins: - Functional Classifications with RDFS reasoning - SKOS categorisations - Inputs and Outputs with RDFS reasoning - Keywords similarity (disabled in v2.0) Note: some of these algorithms have yet to be ported to version 2.0
