Vocabulary for provenance

2018-02-22 Thread Laura Morales
Which vocabulary is a good choice to describe provenance or to describe graphs? I'd like to use something like this "Graph-1" or like this [ "Graph-1" ; ] there are so many vocabularies out there that I don't even know where to start looking at. Is there anything available

Since you mention "provenance", PROV ontology would be one option: https://www.w3.org/TR/prov-o/ But your usage looks more like VoID, more specifically void:inDataset: https://www.w3.org/TR/void/#backlinks PROV and VoID can be combined of course. On Thu, Feb 22, 2018 at 11:35 AM, Laura Morales

I used "provenance" as in "where does this piece of information come from", but it looks like it has a well defined meaning so perhaps I've used the wrong term. Looks like void is closer to my use case indeed, however prov-o seems to have some interesting properties as well. Thanks for the help.

Digressing slightly ... Fuseki (next release) will have the ability to add custom services on datasets. Currently, its the fixed builtin set of query, update, upload etc. Adding a validation service is one such example of a custom addition. Andy On 21/02/18 10:25, Dave Reynolds wrote:

Hi Chris, thanks for that hint. However, it didn't work for me. Even after rebooting the system, the error is still the same: "org.apache.jena.fuseki.FusekiConfigException: FUSEKI_BASE is not writable: /etc/fuseki" However, echo $FUSEKI_BASE gives me the changed directory. Best,

Dear all, my question might be stupid and rather basic, but I cannot find an answer anywhere. So, I set up Fuseki 2.3 as a Tomcat 7 Web app. However, I cannot start it, since "org.apache.jena.fuseki.FusekiConfigException: FUSEKI_BASE is not writable: /etc/fuseki" I now want to change

Hi Christian, Are you sure that the FUSEKI_BASE is defined in the environment when tomcat is run? If you’re running tomcat as a service on Linux, for example, then you would need to add the export to the service or systemd definition that is used to run tomcat. Chris > On Feb 22, 2018, at
