geometry2rdf is a library for generating RDF files for geometrical information (which could be available in GML or WKT). The GML and WKT is manipulated with GeoTools. The current version of the library works with Oracle geospatial databases and relies on Jena.
LabelTranslator is a plug-in developed in the NeOn project. This plug-in is implemented for the ontology development tool NeOn Toolkit and its functionality is the localization of terms, classes and properties, of an OWL ontology creating a linguistic repository model, called LIR.
Recently we have seen a large increase in the amount of geospacial data that is being published using RDF and Linked Data principles. Efforts such as the W3C Geo XG, and most recently the GeoSPARQL initiative are providing the necessary vocabularies to publish this kind of information on the Web of Data. map4rdf is a mapping and faceted browsing tool for exploring and visualizing RDF datasets enhanced with geometrical Information.
Non-Ontological Resources (NORs) are knowledge resources whose semantics have not been formalized yet by an ontology. There is a big amount of NORs that embody knowledge about some particular domains and that represent some degree of consensus.
The OGSA-DAI RDF resource is an extension to OGSA-DAI which adds a new data resource to the framework. The RDF resource extends the existing data resources (relational and XML databases, indexed files) with a resource that provides access to RDF datasets. The access is done either by connecting directly to the database containing the RDF triples (via JenaSDB) or connecting to a SPARQL endpoint at the RDF dataset side. In the figure below it is shown the extension to OGSA-DAI with the new data resource (plus a new resource in development that accesses a RDB2RDF processor).
OWLDoc is a plug-in developed within the NeOn project. This plug-in is implemented for NeOn Toolkit and its function is to add an option in the exportation menu of the tool to generate html documents from an OWL ontology.
Sem4Tags is a multilingual tool that given an input tag and a context generates as a result a DBpedia resource representing the tag meaning. The current version is able to process tags in English and Spanish.
This system implements the SPARQL 1.1 Federated Query extension, by extending the OGSA-DAI/DQP system. The optimisation of these federated queries is done in SPARQL-DQP by identifying well-designed patterns in queries, as described in [1] and [2]. Using such patterns it is possible to apply rewriting rules to federated SPARQL queries and improve the execution time of the queries.
WS-DAIOnt-RDF(S) is a specification for the provision of a service-oriented access mechanism to RDF(S) ontologies.
This OGSA-compliant specification defines the set of data resources and associated access messages and interfaces required for the integration of RDF(S) ontologies in any service-oriented Grid application.
The LIR is a linguistic proprietary model expected to be published and used with domain ontologies. In itself, it has been implemented as an ontology in OWL. The LIR covers a subset of lexical and terminological description elements that account for the linguistic realization of a domain ontology in different natural languages. Thus, its main purpose is to associate multilingual information to ontologies with the aim of contributing to the Ontology Localization Activity.
MARiMbA is a command-line tool, designed with librarians in mind, to transform MARC (MAchine-Readable Cataloging) records to RDF, following Linked Data best practices [1][2][3].
ODESeW (Semantic Web Portal based on WebODE platform) is an ontology-based application that automatically generates and manages a knowledge portal for Intranets and Extranets. ODESeW is built inside the WebODE ontology engineering workbench that provide the following functions:
The Ontology Metadata Vocabulary OMV is a standard proposal for describing ontologies and related entities. The OMV metadata schema is formally represented as ontology and is designed modularly: OMV distinguishes between the OMV Core and various OMV Extensions. The core captures information which is expected to be relevant to the majority of ontology reuse settings, while the extensions allow ontology developers and users to specify task/application-specific ontology-related information (e.g. mappings, ontology evaluation, ontology changes, etc).
R2O & ODEMapster is an integrated framework for the formal specification, evaluation, verification and exploitation of the semantic mappings between ontologies and relational databases. This integrated framework consists of:
Sitemap4rdf is a command-line tool that generates sitemap.xml files for Linked Data sites that have a SPARQL endpoint. Sitemap4rdf queries the endpoint to retrieve a list of all URLs, and generates the sitemap.xml, which then must be uploaded to the site.
WebODE is an extensible ontology-engineering suite based on an application server, whose development started in 1999 and whose support was discontinued in 2006. The core of WebODE was its ontology access service, used by all the services and applications plugged into the server. The WebODE's Ontology Editor allowed editing and browsing WebODE ontologies, and was based on HTML forms and Java applets.
