Future Directions
PURLz 2.0, currently Beta testing, makes major changes to the PURL concept and implementation. Most notably in terms of implementation, the software runs on a Semantic Web framework with information stored in an RDF database. The implementation team intends for the software to provide all the functions of a Web server, excluding the serving of content. Active PURLs, which act similar to a stored procedure in relational databases, are being experimented with to allow a PURL server to actively participate in the creation of metadata describing a Web resource.

Famous quotes containing the words future and/or directions:
“I have often inquired of myself, what great principle or idea it was that kept this Confederacy so long together. It was not the mere matter of the separation of the colonies from the mother land; but something in that Declaration giving liberty, not alone to the people of this country, but hope to the world for all future time. It was that which gave promise that in due time the weights should be lifted from the shoulders of all men, and that all should have an equal chance.”
—Abraham Lincoln (1809–1865)
“I do not like football, which I think of as a game in which two tractors approach each other from opposite directions and collide. Besides, I have contempt for a game in which players have to wear so much equipment. Men play basketball in their underwear, which seems just right to me.”
—Anna Quindlen (b. 1952)
