[UR-WG] APEL vs UR comparison

[Del Cano Novales, C (Cristina)]

Hi Xiaoyu,

Here are the answers to your questions.

1 and 2) The Cpu time recorded by APEL is user+system.

3 and 4) The mappings you suggest seem to be the best choice, so
consider them confirmed.

Kind regards,

Cristina

Hello Cristina:

      Many thanks for you contribution. Could you please also clarify
following properties being used in APEL schemas.

      1). LcgRecord's "BaseCpuTime" and "BaseCpuTimeSeconds" property

          In OGF UR version 1.0, the @urf:usageType attribute is used to
distinguish "user" and "system" usage. So what these two LcgRecord
properties to be mapped, user or system? 

      2). Same as "SumCpu" and "NormSumCpu" properties in Lcg Anonymous
and user aggregate schemas.
      
      3). You also represented 7 extension properties in LcgRecord
schemas. If you have to map them as extension properties being defined
in OGF UR extension framework, what  you would like to express them. You
may specify your options or simply confirm/correct following mappings:

 
------------------------------------------------------------------------
--------------
         |  LcgRecord Property  | UR Property (XPath Expr.)
|
 
|-----------------------------------------------------------------------
-------------|
         |ExecutingSite         |
//urf:Resource[@urf:description='ExecutingSite'             |
 
|-----------------------------------------------------------------------
-------------|
         |SpecInt2000           |
//urf:Resource[@urf:description='SpecInt2000'               |
 
|-----------------------------------------------------------------------
-------------|
         |SpecFloat2000         |
//urf:Resource[@urf:description='SpecFloat2000'             |
 
|-----------------------------------------------------------------------
-------------|
         |EventDate             |
//urf:TimeInstant[@urf:type='EventDateTime'                 |
 
|-----------------------------------------------------------------------
-------------|
         |EventTime             |
//urf:TimeInstant[@urf:type='EventDateTime'                |
 
|-----------------------------------------------------------------------
-------------|


       4). Finally I presume the "MeasurementDate" and "MeasurementTime"
should be mapping to /urf:RecordIdentity/@urf:createTime attribute as
the creation timestamp of a row or a usage record. Could you please also
confirm it as well.
