AW: PROV for SKOS : Inventory of change activities for SKOS

Hi Jean,

Last year, together with Johan De Smedt (Tenforce) and Sini Pessala (National Library Finnland) I’ve started some work on version histories for SKOS vocabularies. It aims to answer common user questions like “What’s new?” and “What has changed?”, when a new version of a vocabulary is published. We have collected a list of use cases and of change categories, was well as running (yet experimental) code for SPARQL queries on named graphs for different vocabulary versions and deltas of versions. The ontologies we worked with are still quite rough (Johan’s dataset versioning ontolgy at https://github.com/JohanDS and a very preliminary skos-history ontology).

Work has stalled in the last months due to other obligations, but everything is online at  (https://github.com/jneubert/skos-history).

What you are trying to achieve sounds very similar. I had in mind to work on the project again in the next weeks anyway.
(@Sini, Johan: How about you?) Perhaps we can join forces here.

Cheers, Joachim

Betreff: PROV for SKOS : Inventory of change activities for SKOS

Hello,

I am working on a application of PROV (Provenance interchange) for SKOS. This work in done to provide a PROV dataset with each new version of a EU controlled vocabulary such as Eurovoc. The PROV dataset will describe all changes since the last version of the controlled vocabulary, and for each the entity source of the change.

In a prov:Entity which will describe the change to be done on the concept, I want to indicate the action to apply on the concept.  For example : change value of the prefLabel from "x" to "y", remove a narrower link to this concept, create a related link with this concept... I image to have a  very limited set of actions and to combine it with the id of the property to change and its value before the change.

Does someone has already worked on a vocabulary of changes for SKOS, so I can start from there ? if not, would someone be ready to work on it together ?

Cheers
Jean
