[uf-discuss] using rel to point to remote meta-data resource for a url identified resource

[adrian skardhamar]

Dear list, this is my first post and I'm a little wet around the ears,  
so please be gentle...

I am working on a project that requires that remote meta-data be  
stored against resources that can be identified by a url - images,  
etc. I am presently considering building a lightweight system that  
would retrieve meta-data (formats to be decided) for these url  
identified resources by using a different url and the rel attribute.  
Perhaps an example would explain it better:

<img src="http://someurl/photo_of_cow.jpg">

becomes

<img src="http://someurl/photo_of_cow.jpg"  
rel="http://someurl/meta_data_about_photo_of_cow">

what is actually held at http://someurl/meta_data_about_photo_of_cow  
is still up for debate.

Am I reinventing any wheels here (assuming that the meta-data itself  
follows standards)? Would using rel in this way upset the microformats  
community in any way? Anyone know of other ways to do this?

Many thanks in advance.
