Introduction

This context set was created to address the need for record metadata searches as opposed to searches within the records themselves.

The identifier for the Record Metadata context set is: http://srw.cheshire3.org/contextSets/rec/1.0/
The recommended prefix for the Record Metadata context set is: rec

Notes

1. The 'within' index is database specific. A database in SQL might accept the name of a table for the record to be within. A file system based database might accept the name of a directory or file containing multiple records.

Examples

1. If your client is only able to display records under 50 kilobytes, you might have a query like:

   dc.title any fish and rec.size < 51200

   to retrieve only files with a title that includes 'fish' and are less than the client's maximum size.
2. If you wanted to find records that were have been recently updated by a user, you might send a query like:

   rec.lastModified > "2002-12-05T18:00:00" and rec.lastModifiedBy="azaroth"
