1. A computer-implemented method for exchanging meta-documents between meta-document servers, comprising: importing, at an importing meta-document server, a meta-document from an exporting meta-document server; the imported meta-document including one or more document service requests fulfilled using one or more document services available at the exporting meta-document server; developing at the importing meta-document server an ontology of namespaces that describe entities in the imported meta-document; binding at least a selected one of the one or more document service requests in the imported meta-document to one of a plurality of document services available at the importing meta-document server when: (a) properties of the selected document service request in the imported meta-document map to properties of one of the plurality of document services available at the importing meta-document server; or (b) the selected document service request in the imported meta-document and one of the plurality of document services available at the importing meta-document server (i) map to the same category in the developed ontology, and (ii) have at least one dictionary and one key in common.

The method according to claim 1 , wherein dictionaries of two document services are in common with each other when dictionaries associated with one of the two document services map a subset of dictionaries associated with the other of the two document services.
