Vinayak Borkar updated VXQUERY-91:
----------------------------------
Labels: gsoc2013 (was: )
> Temporal functions grouped into a common library for byte based storage
> -----------------------------------------------------------------------

> Key: VXQUERY-91
> URL: https://issues.apache.org/jira/browse/VXQUERY-91
> Project: VXQuery
> Issue Type: Improvement
> Reporter: Preston Carman
> Assignee: Vinayak Borkar

> VXQuery utilizes Algebricks and Hyracks to build a XQuery process that can
> run in distributed system. Reviewing the list of query languages build upon
> the same base, there is a common need for temporal functionality. XQuery
> provides a great base for other languages, like AsterixQL, in respect to
> temporal functionality.
> Building a common library of functionality for both XQuery and AsterixQL
> would allow for simplified code base. In addition to only having to implement
> temporal features in one place. The new library could fill in the holes in
> VXQuery's temporal implementation and provide missing temporal features for
> AsterixQL. One library would keep more complex temporal features out of the
> way.
> Key Features for Library:
> - Written in Java
> - Optimized to work with out objects (use byte arrays)
> - Standardized temporal API
> - Useful to other Hyracks applications
> Review of tasks:
> - Consolidate temporal code into one library
> - Update XQuery to use the library
> - Validate all XQuery temporal functions through the test harness
> - Create a patch for AsterixQL for to utilize the new library
> Optional tasks:
> - Temporal Units for the library
> - Additional non-XQuery temporal features
