The Agricultural Information Management Standards (AIMS) Community [1] in cooperation with the Dublin Core Metadata Initiative (DCMI) [2], is pleased to announce the webinar series entitled " SKOS in Two Parts: Generic Tools and Methods for SKOS-based Concept Schemes " [3]. The series will consist of two webinars: "Publishing SKOS concept schemes with Skosmos" (06th April 2016) and "Change Tracking in Knowledge Organization Systems with skos-history" (16th March 2016). The webinars will be presented by Dr. Osma Suominen (National Library of Finland) and Joachim Neubert (ZBW Leibniz Information Centre for Economics).


+++Publishing SKOS concept schemes with SKOSMOS (06th April 2016) [4]+++
With more and more thesauri, classifications and other knowledge organization systems being published as Linked Data using SKOS, the question arises how best to make them available on the web. While just publishing the Linked Data triples is possible using a number of RDF publishing tools, those tools are not very well suited for SKOS data, because they cannot support term-based searching and lookup.
This webinar presents Skosmos, an open source web-based SKOS vocabulary browser that uses a SPARQL endpoint as its backend. It can be used by e.g. libraries and archives as a publishing platform for controlled vocabularies such as thesauri, lightweight ontologies, classifications and authority files. The Finnish national thesaurus and ontology service Finto, operated by the National Library of Finland, is built using Skosmos.
Skosmos provides a multilingual user interface for browsing and searching the data and for visualizing concept hierarchies. The user interface has been developed by analyzing the results of repeated usability tests. All of the SKOS data is made available as Linked Data. A developer-friendly REST API is also available providing access for using vocabularies in other applications such as annotation systems.
We will describe what kind of infrastructure is necessary for Skosmos and how to set it up for your own SKOS data. We will also present examples where Skosmos is being used around the world.
Skill level: Intermediate. A working knowledge of SKOS and a basic knowledge of triple stores and SPARQL queries are presumed.

The session is open to anyone but places are limited. If you are interested to attend the webinar, send an e-mail to AIMS at, containing the following information: your name, affiliation, role and country.

+++Change Tracking in Knowledge Organization Systems with skos-history (16th March 2016) [5]+++
When a new version of a vocabulary is published, users want to know "What's new?" and "What has changed?" Vocabulary managers had differing strategies to answer these questions—relying on internal logs of the vocabulary management system or the intellectual collection of changes deemed relevant. These methods generally are not available to third parties using a vocabulary, or for example are trying to keep vocabulary mappings up to date. Having vocabularies published in SKOS as RDF triples has changed this situation: Vocabularies can be compared algorithmically, and deltas between versions can be computed. This data can be loaded into a version store, and evaluated by SPARQL queries. Therefore, the published versions alone are sufficient to get the differences.
The webinar will explain how you can create a version store, how skos-history interlinks versions and deltas, and how queries can get a grip on added or removed concepts, on changed notations, or on merges and splits of concepts. We will show how aggregated change information about a concept scheme can be obtained, and how the complete change history of a single concept across multiple versions can be traced. Finally, you will learn how you can adapt skos-history queries to the features of a particular concept scheme in which you are interested.
