Re: Fwd: [periodicals] Announce: Sample Linked Periodical Data

Hi Kingsley

Very nice!


Thanks. This is the first of several interesting datasets that'll come from
the dataincubator project.

Its still early days for the dataincubator project. As it is potentially an
umbrella project for a number of independent activities its difficult to
make assertions one way or another as it'll depend on the community members
to ensure these tasks get done.

However, for those datasets hosted within the Talis Platform, its a simple
matter (i.e. a single HTTP POST) to generate an RDF snapshot of a dataset
for backing up and re-publishing elsewhere. So the tools are in place and
hopefully general encouragement towards community norms will do the rest.
I'm currently investigating how to automatically push datasets hosted as
part of the Talis Connected Commons [1] into the Amazon Public Datasets
programme, so this will offer another route.

As the periodicals dataset is at a very early stage I don't plan to provide
a dump just yet -- there's plenty more data to accumulate and discussion to
be had around the modelling. However for anyone that wants to create one,
the Ruby scripts are in the open source project. In the meantime, I'll
update the SPARQL Endpoints page to list the endpoint [2] which is already
listed in the Void description [3] :)

Cheers,

L.
