Hi Paul,
Yes, thank you for bringing the metaschema back to my attention. I had
looked at this before and, yes, was very much turned off by the lack of
documentation. (Still am.)
As a *listing* of kinds of attributes, this is quite helpful, and should
be embraced by any design scope. I like the fact that properties can map
to entity types; that seems to be a useful design. But its structure and
use as is does not appear directly usable for what I am seeking.
Am I missing something?
Thanks, Mike

I would say take a look at the Freebase Metaschema

The documentation is atrocious, but this information is available in
standards-compliant (i.e. won't crash your tools) format

One really cool thing is that it can map property paths to properties,
which is essential given the heavy use of compound value types in
Freebase.

Hi All,
I have been looking for an ontology that organizes and describes possible
characteristics or attributes for common entity types, such as what might be
found in a key-value pair in Wikipedia infoboxes and such.
I have had no luck finding such a vocabulary or ontology. The closest
representation I found was one related to sensors and the Internet of Things
(IoT) [1]. The Wolfram Language also has an interesting structure around
units [2]. Biperpedia has recently been discussed by Google [3], but no
actual ontology or structure yet appears available for inspection.
Does anyone know of a general ontology for capturing record/entity
attributes or characteristics (properties)? I know some domains like
biomedical may have partial approaches to this, but I'm seeking something
that has as its intent being a general-purpose attribute reference.
Suggestions or pointers would be greatly appreciated.
Thanks, Mike
