The Asset Description Metadata Schema (ADMS) v1.00 is a metadata vocabulary to describe semantic standards (e.g. core components, domain models, schemas, thesauri, taxonomy, or code lists) on the Web. This article shows how you can generate ADMS descriptions of your semantic assets from a spreadsheet using the RDF extension to Google Refine released by DERI‘s Fadi Maali and Richard Cyganiak.
On April 18, ADMS v1.00 was released on Joinup (see announcement by WG Chair), under the ISA Open Metadata Licence v1.1. ADMS is an initiative of the ISA Programme of the European Commission  which formed a multidisciplinary working group of researchers, EU institutions, standardisation bodies and other experts.
ADMS v1.00 helps you document the features of your semantic standard such as its name, description, theme, asset type, representation technique, origin, publisher in a machine-readable way, which can be either ADMS XML or ADMS RDF format. Such machine-readable metadata in ADMS format brings the following benefits:
The spreadsheet template contains all concepts and fields in the ADMS v1.00 conceptual model. To describe your semantic asset you must fill in the repository, semantic asset*, semantic distribution, contact information, publisher*, licence*, documentation, and item sheets. Sheets marked with a * -symbol are mandatory. The spreadsheet also contains a number of sheets with pre-defined controlled vocabularies, such as asset type, licence type, representation technique, file format, etc. These sheets help you to select the right codes to use, but you should not update them.
Install Google Refine and the RDF extension on your system following the installation guide. Create a new project in Google Refine and import the spreadsheet you created in step 1. The screenshot below indicates which parameters to fill in.
The Google Refine RDF extension allows you to determine the intended structure of the RDF data by drawing a template graph. You can manually edit the RDF Skeleton by clicking “RDF” > “Edit RDF Skeleton...” in Refine.
To save you the trouble of adding a mapping from the spreadsheet to the ADMS RDF vocabulary, you can re-apply the operation history. The operation history contains all operations previously carried out to build the RDF Skeleton for the spreadsheet template. To apply the operation history:
Now everything is in place to generate and ADMS RDF file, containing your semantic asset descriptions. Click “Export” > “RDF in RDF/OWL” or “RDF in Turtle”.
You now have obtained an RDF description of your semantic asset in either Turtle or RDF-XML. You can validate your RDF file using the W3C RDF Validator. You can save your metadata on your web page and share it with the forthcoming federation of semantic asset repositories on Joinup.
