Tyagi You could use server fields - see
xdmp:set/get-server-field. ( http://docs.marklogic.com/xdmp:set-server-field ) Or you can save a map as a document ( first part of below ) and access it as per second part of below, which could be wrapped into a small utility function. let $map := map:entry("A",1) + map:entry("B",1) return xdmp:document-insert("/map.xml",document{$map}) ; map:map(fn:doc("/map.xml")/*) There won't be any disk overhead if you're accessing frequently as it will be in the expanded tree cache.

Any suggestions about how to implement it? May be I can put it in a different Xquery module and import it?

Avoiding side-effects when none is required will save you some (hard-to-track-down) troubles.
