Shaik, If you are using ML 7, it seems like a pretty good use case for RDF here
For each pair of document you will only have to store one triple <sem:triple xmlns:sem="http://marklogic.com/semantics";> <sem:subject>http://example.com/xml1</sem:subject> <sem:predicate>http://example.com/pred#areRelated</sem:predicate> <sem:object>http://example.com/xml2</sem:object> </sem:triple> To know if this will fit, can you explain, what kind of processing you do with this information ?
