[Css-csts] Inconsistency in service object identifier names

[John Pietras]

Yves,

Section C4.2 in CSTSFW R-0.19 defines the "three sub-numbers" of a given
services's servicesIdentifier OID as:

i.                 (service name)DerivedServices;

ii.                (servicename)ExtServiceParameters;

iii.               (service name)ExtServiceProcedures.

 

However, in the CCSDS-CSTS-SERVICE-TYPE-ID module in the recent R-0.20
ASN.1 document, the following OID names are defined:

mdDerivedServices 

mdExtServiceParam     

mdExtProcedures 

 

trkDataSvcderived                    

trkDataExtServiceParam                       

trkDataExtProcedures               

 

ruftDataSvcderived                  

ruftDataExtServiceParam          

ruftDataExtProcedures              

 

 

"mdDerivedServices" is already consistent with section C4.2, but
"trkDataSvcderived" and "ruftDataSvcderived" are not. Shouldn't they be
"trkDataDerivedServices" and "ruftDataDerivedServices"?

 

There's also an inconsistency between C4.2's
"(servicename)ExtServiceParameters" and "mdExtServiceParam",
"trkDataExtServiceParam", and "ruftDataExtServiceParam".

 

While it is true that these are all just names and they are not required
to have the same construction, having them follow a common construction
makes connecting the concepts and instances easier.

 

Best regards,

John
