<div>After studying geo metadata interoperability and discovery quite some time I came to a similar conclusion like our fellows of digital library science, namely that we have (1) an interoperability and (2) a chicken-and-egg-problem: There will be no single 'geometadata Google web app' nor on a 'one-size-fits-all' standard. It's probably even not desirable.
</div>

<div>So what's perhaps reasonable is to take a stepwise approach beginning with a simple solution. In order to get 100% interoperability to move metadata around we need to agree to an object model, an encoding and a protocol. Actually - because this seems not 100% feasible - we need mappings (conversions or crosswalks as they say in OAI-PMH) between different object models.
</div>

<div>Regarding the object model something like a sligthly extended Dublin Core element set could be a solution for the first step. Regarding the protocol there is still more discussion needed. Actually Raj just made 'a modest CSW proposal' at the dclite4g list:
