Re: Please update your resource in the LOD Cloud Diagram

**

*Hi everyone,*

*

We want to address some of the comments and  suggestions mentioned in 
this thread.

While we are keen to use metadata from resource publishers wherever 
possible, we still require that your resource is listed in Datahub as we 
do not have the capability to crawl the Web looking for VoID 
descriptions at this moment.

  *

    In DataHub there is an option to upload VoID descriptions. Please
    upload here and we will attempt to extract the metadata from the
    VoID file.

  *

    For VoID file to be useful, it would have to contain
      "dcterms:subject" property that describes the topics contained in
    the dataset and "void:Linkset" describing links to other datasets
    and number of triples linking to said dataset. The target of any
    linkset must correspond to a VoID file listed in Datahub; e.g., to
    link to European Nature Information System (EUNIS) you should link
    to the VoID description listed at Datahub:
    http://eunis.eea.europa.eu/void.rdf.

  *

    For now, if you have VoID file that contains this information, and
    for any reason you don't want to publish it on DataHub, you can send
    it to us and we will add it to our system.

We are aware that there is a dataset validation tool 
(http://validator.lod-cloud.net/) available, but we are not currently 
maintaining it our using it to check the validity of a dataset. If you 
are unsure as to whether your Datahub record is suitable please email us 
and we will check that it appears correctly in the diagram.:

As there have been multiple requests, we will postpone the  generation 
of the diagram till next weekend (24.06.17)

Kind regards,
