as suggestion for the book name I suggest something sharp that allow to 
grasp the content of the book from the title. Foe instance

Lifecycle for Long Term Data Preservation
Long Term Data Preservation Lifecycle
Data Management for Long Term Preservation

Just a couple of ideas. I see that the term "Long Term Data Preservation" 
it is very much used in the community and I am proposing to capitalise on

Hi all,
Please find below my analysis, and proposed set of phases by end of the 
Thank you very much Mike and David for your material.
=>First: general feeling:
1.I?m ok with your last email?s Mike (format). Furthermore, the EXCEL 
sheet on activities shows that terms and points of views differ, but we 
have points of intersection. The differences in the main phases are also 
2.Thank you David for your last email on the need for annex: we need 
indeed an annex describing the relationships with other community 
standards such as LTDP.
3.I?m also in favour to add a section or annex explaining the 
relationships with the other standards OAIS, PAIMAS/PAIS showing the place 
of this one.
4.Following different exchanges with Mario Merri (quotation ?can't we 
change the name of Information Curation Process to something more 
meaningful??), LOTAR ? the term ?curation? seems hard to understand. The 
title may be decided at the end, but the use of terminology not. I suggest 
that we try to find something different.
Something like: ?Information Lifecycle and Long term usage?, ?Information 
usage over its Lifecycle? ?
Crucial terms: lifecycle, data usage, data management
5.Generally speaking, we should be careful with the terminology (use of 
metadata ?), and keep the coherence with the OAIS, and keep consistency 
between them.
=>Second: structure of the ILF document
1.Information Topics vs activities
This issue has been discussed at length. My feeling is that both may be 
present, with a focus on information to be gathered as decided. I?d like 
to keep a list of main activities as proposed in section 3.1
Section 3: the lifecycle framework: the main stages and information to be 
Section 3.1 Information Lifecycle stages
I?m fully ok with this. Why not include here the detailed description of 
the phases (sections 3.3.1 till 3.3.4).
Section 3.2: Information topics
Section 3.3 Staged curation information -> change ?curation?
Non normative annex: from David: ?non-normative annexes which map the 
terminology to existing practice. The obvious one is the ESA-LTDP work. 
Being non-normative it should not cause too much controversy. ?
Non normative annex: schema showing ILF and other CCSDS archiving 
standards + relationships
=>Third: Comments on Topics
The existing draft list proposed by David contains different levels of 
topics in my opinion.
David, is there a particular order in the table of topics?
For example: 
Some topics deal with categories of info (e.g. Data, Rep Info, Provenance, 
SIP, but OAIS ?context? does not appear), others deal with characteristics 
of Data (e.g Discoverability), others with transfer of responsibility 
We also have to check the list of associated issues:
For example how about having ?Designated community? in ?Data topic? 
instead of ?handover topic?, as this community uses the data during 
Operation and Exploitation stages.
How about having the preservation objectives in the proposal topic?
Catalog could be used in ?discoverability topic? ?
One of the first tasks we have is to consolidate this list.
=>Fourth: activities
We have to find a way to express link between the lifecycle stages and 
associated preservation activities with the topics, and to consolidate the 
?typical activities?. Keeping our strategy, we don?t need to say a lot.
=>Fifth: Proposal for a set of phases to produce the ILF standard
September: Consolidate the list of topics and consolidate the typical 
Till mid-October: High level links between activities and topics
Mid October-end November: Develop the topics
December: Link with CCSDS archiving standards, Mapping with LTDP, Internal 
What do you think?
