Metadata exchange


I’ve been thinking about how to best exchange metadata. To give an example: DSI is categorizing and analyzing projects based on rough four categories: Open hardware, Open networks, Open data and Open knowledge. If I was given a choice at the moment of describing my project in any catalog to add those tags/categories it would help a lot DSI. Same goes for the specific needs/metadata of all other catalogs.

It seems to be that we should have a big part of metadata standardized, but also allow for extensions that could be easily propagated via platforms.

What’s your take on that?
