An organization ontology : Final steps
The next steps in developing our ontology involve one more set of changes (linking to OPMV) and, most importantly, publishing the ontology somewhere. These aren’t the “final” steps as far as the ontology is concerned, it will need to evolve as people gain experiences applying it and give feedback on design and naming issues. However,…

An organization ontology: Second draft
This is the fourth in our series of postings on the design of an organization ontology. The focus this time is on revising the ontology in the light of feedback and reflection. Review Reviewing the results of our draft with respect to the various design guides then we notice that we have failed to follow…

An organization ontology: First draft
This is the third in our series of posts recording the (currently ongoing) process of developing an organization ontology. Here we sketch an initial design. Taking the initial requirements we now look at each part of the domain scope and identify the core classes, properties and design patterns. This sketch is designed to cover all…

An organization ontology : Requirements
Background The data.gov.uk linked data project found itself in need on an ontology or vocabulary to support linked data publishing of government organizational information. A check for existing ontologies didn’t turn up an ideal solution so we decided to develop one. This is the first of a series of posts describing the process we went…

An organization ontology : Survey
This is the second in our series of posts recording the (currently ongoing) process of developing an organization ontology. Here we are focused on surveying the options that already exist to confirm we haven’t missed anything. Check for existing ontologies By far the best way to define an ontology is to just find one and…

Semantic Data Exchange
Semantic Data Exchange (SDX) was an investigation project looking at the role of information intermediaries for government linked data. This was a project funded by TSB (Technology Strategy Board). The work on SDX led to, supported and eventually exploited the Linked Data API we jointly developed with Jeni Tennison and Leigh Dodds. We gave a…

Using Interval Set URIs in Statistical Data
Statistical publications generally include at least one dimension comprised of the time intervals over which data has been aggregated. Linked data vocabularies for representing statistical information, such as SCOVO and current SDMX/Linked-Data collaborative activities refer to time intervals as ‘things’ or ‘objects’ rather than as literal values. This will typically involves the assignment of a…

Epimorphics designing ECO, a core domain ontology for Life Cycle Analysis
As the next step in developing the Earthster vision of creating a web of linked open sustainability data, Epimorphics is designing a core domain ontology for representing Life Cycle Analysis information about products. The Earthster Core Ontology (ECO) is a core domain ontology for life cycle analysis which is capable of representing models of product…

Will linked data on data.gov.uk survive an election?
Last week I attended a cross-political party dinner given by the Technology Strategy Board(TSB) to promote their Digital Britain programme to policy-makers. There were about 20 of us there – mostly politicians, a number of people from the TSB and a few people from industry. Epimorphics is currently working on two TSB (part-)funded feasibility studies…

An RDF to JSON converter on Google App Engine
As part of our work on the SDX project we felt one requirement was to enable typical web developers to exploit the RDF linked data in a simpler, more developer friendly form. In particular it would be nice to be able to access an RDF model of a resource as JSON to simply using it…
