Metadata Workshop held on March 1-3, 1995, in Dublin, Ohio addressed the issue of appropriate metadata elements for document-like objects and identified an initial set of thirteen elements called the Dublin Core[\protect\citeauthoryearWeibel1995].

By peer agents we mean agents that are capable of solving the task that another agent has at hand.

Note that this mode of cooperation unfortunately carries the same name as our use of the term distributed case-based reasoning for agents more generally doing case-based reasoning in a distributed manner. The name for this mode of cooperation was introduced in [\protect\citeauthoryearPlaza, Arcos, &Mart´n1996] where cooperative CBR was used for agents more generally doing case-based reasoning in a distributed manner. In order to avoid confusion, in this paper, we use the acronym DistCBR for this specialized FPL cooperation mode and the terms cooperative CBR and distributed case-based reasoning are used interchangeably for the more general situation of agents doing case-based reasoning in a distributed manner.

In these examples, when we talk of agents we mean computational agents that develop their case bases from the experiences of different employees and are equipped with automated tools for exploiting such experience like case-based reasoning tools. However, the methods presented here would also be applicable for mixed-initiative systems where computational agents and humans are treated as ``agents'' in an integrated multi-agent system.
