Publishing university linked data with LMF

[Alex Donnini]

Hello I'm publishing Linked Data for University of Roma Tor Vergata. I'm going to import organization data with the attached file.  Triple from file seems not completely imported also if the file is validated by using protege. If you access http://opendata.ccd.uniroma2.it/LMF/resource/nodo_0 you can see organization root properties and if you compare them with the file some properties are missing, like vcard and tvo attributes.

Do you have any suggestion?

Next step is to publish also dataset files as resouces and to set search APIs.

Thanks

Hi Alex,

you are mixing datatype and object properties... syntactically could be
valid, right, but probably has a different meaning than what you want.

For instance, you have something like:

<rdf:Description
rdf:about="http://opendata.ccd.uniroma2.it/LMF/resource/nodo_0">
<rdf:type rdf:resource="org:FormalOrganization" />
<org:classification
rdf:datatype="xsd:anyURI">http://opendata.ccd.uniroma2.it/LMF/resource/TipoNodo_1</org:classification>
</rdf:Description>

Where you probably want something like:

<org:FormalOrganization
rdf:about="http://opendata.ccd.uniroma2.it/LMF/resource/nodo_0">
<org:classification
rdf:resource="http://opendata.ccd.uniroma2.it/LMF/resource/TipoNodo_1" />
</org:FormalOrganization>

You can visualize the graph using the RDF Validator, for example:

http://www.w3.org/RDF/Validator/

I'd strongly recommend you to take a look to the RDF/XML syntax if you
are going to edit manually such kind of data:

Hope this helps.

Cheers,

Hi Sergio thanks a lot, I studied, understood and I'm going ahead, as you can see from target :)

The dataset/graphs/context are not yet ready, I 'm studing a way to publish linked open data by using LMF and as I told you the next step is to publish dataset files in various formats with the digital library functionalities available in LMF/Marmotta.
