Unless I'm misunderstanding what you're after, link resolvers don't really "recognize metadata" from databases -- library link resolvers are sent metadata in an OpenURL when a user clicks a link that points to her resolver.  Unless you plan on maintaining accounts for libraries and implementing IP address recognition so that each library's users will see a link to their institutional resolver when using your database (which is what the commercial databases do), the best approach might be to take advantage of the OCLC OpenURL resolver registry -- instead of having to generate OpenURLs that include institution-specific base URLs, you generate OpenURLs that point to worldcat, and the registry reformulates the OpenURL to point to the resolver associated with the user's IP address.  This is the approach used by the Bibliography of Asian Studies at U Michigan; you might want to contact someone there for advice.  Of course this approach only works for institutions whose resolvers are registered with OCLC and when users either have an institutional IP address or are going through an institution's proxy server.

I imagine the code you use to generate the actual OpenURLs would likely be similar to the code you're using to generate COinS et. al.
