Linked Media Framework

The Linked Media Framework is an easy-to-setup server application that bundles central Semantic Web technologies to offer advanced services. The Linked Media Framework consists of LMF Core and LMF Modules. LMF Core The core component of the Linked Media Framework is a Linked Data Server that ... [More] allows to expose data following the Linked Data Principles: The Linked Data Server implemented as part of the LMF goes beyond the Linked Data principles by extending them with Linked Data Updates and by integrating management of metadata and content and making both accessible in a uniform way. Our extensions are described in more detail in LinkedMediaPrinciples. In addition to the Linked Data Server, the LMF Core also offers a SPARQL endpoint. [Less]

easyrdf

EasyRdfEasyRdf is a library designed to make it easy to consume and produce RDF. It was designed for use in mixed teams of experienced and inexperienced RDF developers. It is written in Object Oriented PHP. During parsing EasyRdf builds up a graph of PHP objects that can then be walked around to ... [More] get the data to be placed on the page. Data is typically loaded into a EasyRdf_Graph object from source RDF documents. The source document could either be an RDF file on the web or the output of a Construct or Describe SPARQL query from a triplestore.

structwsf

structWSF is a platform-independent Web services framework for accessing and exposing structured RDF data. Its central organizing perspective is that of the dataset. These datasets contain instance records, with the structural relationships amongst the data and their attributes and concepts defined ... [More] via ontologies (schema with accompanying vocabularies). The structWSF middleware framework is generally RESTful in design and is based on HTTP and Web protocols and open standards. The initial structWSF framework comes packaged with a baseline set of about a dozen Web services in CRUD, browse, search and export and import. All Web services are exposed via APIs and SPARQL endpoints. Each request to an individual Web service returns an HTTP status and optionally a document of resultsets. [Less]

RDF.rb

RDF.rb is a pure-Ruby library for working with Resource Description Framework (RDF) data.

neon-plugins

The aim of the NeOn (Networked Ontologies) project is to advance the state of the art in using ontologies for large-scale semantic applications in the distributed organizations. Particularly, we aim at improving the capability to handle multiple networked ontologies that exist in a particular ... [More] context, are created collaboratively, and might be highly dynamic and constantly evolving. This project covers the plugins for NeOn core. [Less]

ldspider

The ldspider project aims to build a web crawling framework for the linked data web. Requirements and challenges for crawling the linked data web are different from regular web crawling, thus this projects offer a web crawler adapted to traverse and harvest sources and instances from the linked ... [More] data web. The project is a co-operation between Andreas Harth at AIFB and Juergen Umbrich and Aidan Hogan at DERI. [Less]
