Hi Kendall,
One popular approach is to maintain an additional metadata.xml document, which contains all metadata for the documents stored in a database. Here is a simple example for maintaining a timestamp: ____________________________
* Creation:
db:create('db', <meta/>, 'metadata.xml')
* Insertion:
let $path := 'new-doc.xml' let $doc := <xml/> let $meta := element doc { attribute path { $path }, element timestamp { current-dateTime() } } return ( db:add('db', $doc, $path), insert node $meta into db:open('db', 'metadata.xml')/meta )
* Retrieval:
let $path := 'new-doc.xml' return db:open('db', 'metadata.xml')/meta/doc[@path = $path]
* Deletion:
let $path := 'new-doc.xml' return ( db:delete('db', $path), delete node db:open('db', 'metadata.xml')/meta/doc[@path = $path] ) ____________________________
Cheers, Christian

Unless there is now a standard way to associate metadata with documents and collections, is there a preferred method?
I could try to ensure that there is always a unique id that can be derived from combination of an id attribute or element in the document + the document’s document uri, then have separate metadata documents that are associated with the unique id. Is there an obviously better approach?
