[Moims-dai] Questions about the OAIS

[David Giaretta]

Hi Claire, Stéphane

 

Sorry for not replying earlier. Thanks for the reminder.

 

On another subject, I have news questions about the OAIS:
-          In section 4.3.4, we talk about functional area, is there a difference between function area and functional entity ?

 

Well spotted – I think that should be Functional Entity – I’ll add that to the review.oais.info site so we do not forget – see http://review.oais.info/show_bug.cgi?id=216 .


-          In section 5, in the sentence “Even more daunting, as operating systems evolve, is  maintenance  of  operational  software  as  a   part  of  the  Representation  Information,  which   means  that  it  is  essential  for  the  preservation   of  Content  Information.” : 

Does the “it” refers to the Representation Information or the operational software ? What it is meant by “operational software as part of the Representation Information” ?

 

My understanding is that the “it” refers to the operational software. 

 

The point is that operational software (which I understand as being the software of the operating system) may be necessary to understand and use the Data Object – i.e. needed to run some specific analysis software to extract and analyse data, for example some specific version of DEC Unix – therefore it is a part of the Representation Information i.e. it is one part of the overall Representation Information needed to understand and use the Data Object.

 

I hope that helps, and I’d welcome any additional comments/answers.

 

Regards

 

..David

Dear all,
 
Sorry for my absence these last weeks, I have lot of running projects currently. About the CCSDS meeting in May, are there some of you planning to go ?
 
On another subject, I have news questions about the OAIS:

Thanks again for your help.
