======Acquisitions/Serials - notes on integration======

We want to leverage attribute support for additional metadata. The attribute model is based on [[http://www.w3.org/TR/rdf-concepts/#section-triples|triples]] and can be queried in //WebTools//
but we want attribute support directly in //Desiderata//, specifically within the //Advanced Search//
option.

We change the layout here to include attributes. This is fairly basic, the search is only carried out if a //Attribute Value// is included, this could be expanded, but it seems likely that the vast majority of searches well be based on this criteria:

Attributes are not included in the default keyword searching, which is based on [[http://lucene.apache.org/|Lucene]], and advanced searching uses a constraint approach for modifying queries.

So, for example, this search is constrained by the attribute criteria, which can be extracted from the search by clicking on the //X//.
