SRU-CQL servlets

Explain response

The explain response should, ideally, provide a list of ISOCatted indexes as possible search indexes.

Example (tentative):

 <indexInfo>
  <set identifier="http://www.isocat.org/datcat" name="isocat"/>
  <set identifier="clarin.eu/schema/ccs-v1.0" name="ccs"/>

  <index id="?">
    <title lang="en">Part of Speech</title>
   <map><name set="isocat">partOfSpeech</name></map>
 </index>	

 <index id="?">
    <title lang="en">Words</title>
   <map><name set="ccs">words</name></map>
 </index>	

  <index id="?">
    <title lang="en">Phonetics</title>
   <map><name set="ccs">phonetics</name></map>
 </index>	

</indexInfo>

Search context

Restricting the search space shall be done via x-cmd-context parameter (obsoleting: x-cmd-collections).

Data Views

All dataviews of specific types should be the same in all implementations. That is, if a service presents results a KWIC, that should be the same KWIC in all services. Here we propose one encoding for several types of dataviews. All implementing services must conform.

 Full Resource:: The full resource, e.g., an EAF file. could also be a url.

 Geolocation:: A location on a map.

 Annotations:: A bunch of annotated text.
                     We start by supporting the TCF and EAF format as they have existing viewers.

== FCS webservice ==

REST webinterface that does the aggregation (Metasearch) (map/reduce).
Should support the x-cmd-context as given by the metadatasearch service, or by the user in the federated search website.

PazPar2 is a federated search service (metasearch).
