Semantic Crunchbase to FOAF mappings
Andreas Harth
I've written a few mappings from semsol's semantic crunchbase to FOAF.
The OWL file defining semsol's properties and classes as subproperties and
subclasses of FOAF and RDFS is at [1].
A few observations re data quality:
* feed: URIs should be http: URIs since feed: is not an official protocol
* there are some typos in URIs a la htp://
* there are three versions of images with different filenames but
identical content
Re semantic crunchbase:
* it would be great to model dates (e.g. funded and born) using the XML
schema
date datatype rather than separate properties for year, month, and day
* first_name and last_name could be concatenated and mapped to foaf:name
* email_address could include mailto: and then mapped to foaf:mbox
If you need other mappings please let me know and I can include them in [1].
Regards,
Andreas.

Ah, cool.
I'm working on mapping/inference scripts, this is going to help :)
Cheers,

Hi,
I've just activated a faceted browser[1] for Semantic CrunchBase' RDF
store. It's an early version (limited caching, no previews, etc.), but
it seems to work for basic data exploration.
Cheers,
Benji
