A group of us within ETSI are working on the definition of a structure for associating electronic signatures, based on the XAdES (ETSI TS 101 933) and CAdES (ETSI TS 101 703), with one or more objects held in a ZIP based structure. The aim of this structure is to be compatible with use of OCF (OEBPS Container Format), ODF (Open Office) and UCF.

Currently, the ODF specification defines a syntax and file name for the signature "documentsignatures.xml" which is different from the "signatures.xml" syntax defined in OEBPS Container Format (OCF) 1.0 and also used in the Universal Container format defined by Adobe:

It would greatly assist us in applying the ETSI advanced signature formats (which extend the XML and CMS standard formats) to container formats such as ODF if this ODF syntax and filename was consistent with that used in other container formats.

I would also like to bring to your attention that reference from part 1 section 3.16 to section 2.4 of part 3, should reference part 3 section 5. Also and that in part 1 3.16 text mentioning "macrosignatures.xml" needs updating as this in not mentioned in part 3.

Due to shortage of time following the holiday period this is an individual contribution, but it is our aim to keep ODF informed of ETSI's ongoing work on Associated Signatures and its use with container formats such as ODF.
