SNIK: Hybrid usage along with SPARQL Update

[KonradHoeffner]

SNIK

• https://www.snik.eu/

• SNIK is a large ontology with the SNIK meta model

• Challenges caused by meta model and OWL restrictions: one fact is represented by several triples, OntoWiki does not warn user when deleting parts of such a fact, rendering it invalid. This is explained in more detail in LinkedSpending: Large amounts of data and complex structure #2.

• OntoWiki is used for selective changes and Semantic Web inexperienced users

• SPARQL Update queries are used by technical users and for sweeping changes involving many different resources at once.

• This presents a problem with the history function of the OntoWiki, as it isn't the only place where the data changes.

• Backlinks would be useful for that project, OntoWiki shows all ?x ?y ?z triples for a given subject ?x but it would also be great to see the inverse ?z ?y ?x, as sometimes the direction is arbitrary, especially with symmetric properties where we don't materialize all implied triples.

• We linked to OntoWiki from SNIK Graph and the SNIK LodLive RDF Browser. This is possible because you can specifiy the graph and model in the URI. It would be great if there were an automatic graph determine function though, where you could just give the URI of the resource alone.

• The "bot attack" problem of accidental resource deleting when the system configuration gets reset still (version 1.0.0) occurs. See https://symbolicdata.github.io/OntoWiki.

Thanks, fixed it.
