For now the open org namespace: http://purl.org/openorg/ directs to this page, as we plan the vocab.

The recommended prefix is "oo".

Dataset validity dates

oo:bestBefore

Sub-property of 'dcterms:date'. Relate a dataset or RDF document to the date after which the publisher recommends it should be treated with caution. For example a resturant may publish a menu but want to warn people that after year it might be a bit wrong, but is still potentially useful. When ordering a take away, last year's menu is better than no menu at all, but you should still be warned that it might be out of date.

This is primarily aimed at assisting humans consume the results of this data, but it may also be used as a filter to keep potentially incorrect data out of a SPARQL database.

oo:doNotUseAfter

Sub-property of 'dcterms:date'. Relate a dataset or RDF document to the date after which the publisher recommends it should not be used as anything other than historical data.

other useful terms

It is recommended you use dcterms:modified to indicate the date the dataset was last updated. See also voID: http://vocab.deri.ie/void/guide

Press info

These are used by the Press Info recipe to extend FOAF.

Misc

oo:twitter_hashtag

This is used to relate a concept to the Twitter hashtag people are using to talk about that thing.

We've created the twitter_hashtag in the open org namespace. A hashtag can be related to a concept, location, event, or anything. A combination of hashtags may be used in one literal to indicate that it is that combination of hashtags which is associated with that resource.

Having two oo:twitter_hashtag properties, however, would indicate that either is used to refer to the same thing (not recommended).

<oo:twitter_hashtag>#myconf2010<oo:twitter_hashtag>

or, to indicate a combo hashtag:

<oo:twitter_hashtag>#myconf2010 #track2<oo:twitter_hashtag>
