  <DIV></DIV>Hi, <BR><BR>IMHO, I think we need to simple discuss a quick 
  cost/benefit analysis of this endeavor.&nbsp; Why do we need this grammar? 
  What it enables? Why is that important? and then How would we go about doing 
  it... and what resources are involved.&nbsp; Basically, is the juice worth the 
  squeeze.&nbsp; The basic thinking I have on this is that it would be a good 
  thing to know the shape of the catalog in so far as the shape of it will 
  enable new capabilities.&nbsp; If the benefit of knowing the shape of this box 
  "only" makes life easier for those doing machinations at that level... then... 
  well, that is what we should find out.&nbsp; Is it on fire? Or is this a 
  Cassandra moment - as I have been having on this topic for over a year and a 
  half.&nbsp; Thus far it has not moved into the realm of "on fire" which leads 
  me to perhaps believe that this kind of thing is best left to a select and 
  motivated few that should go off and fix it and then report back so we all can 
  leverage it.&nbsp; I don't think there needs to be a lot of sausage makers 
  here.&nbsp; This is why I proposed that Stephen start a working group if one 
  is not already there.&nbsp; <BR><BR>Oops.. that reminds me, making a working 
  group page fell off my radar after the F2F... I will do that.&nbsp; For now I 
  recommend appending this task to that of the Information Architecture (Data

            yesterday with Estani and Martina, so I'll try to sum some points up 
            here. I am not too familiar with the ESG publishing process, so I 
            can only guess that Stephen's #1 has something to do with the 
            bending of policies that are for pragmatic reasons not enforced in 
            the CMIP5 process. (My intuition is that *ideally* it should be 
            impossible to make data available without going through the whole 
            publication process. Please correct me if I am misunderstanding 
            this.)<BR></BLOCKQUOTE></BLOCKQUOTE>

          <BLOCKQUOTE type="cite">Most of what I have been thinking about 
            however concerns point #2. I'd claim that the risk here should not 
            be underestimated; data consumers being unable to find the data they 
            need is bad ("the advanced search issue"), but users relying on 
            deprecated data - most likely without being aware of it - is 
            certainly dangerous for scientific 
        credibility.<BR></BLOCKQUOTE></BLOCKQUOTE>
        <BLOCKQUOTE type="cite">
          <BLOCKQUOTE type="cite">My suggestion to address this problem is to 
            use globally persistent identifiers (PIDs) that are automatically 
            assigned to data objects (and metadata etc.) on ESG-publication; 
            data should ideally not be known by its file name or system-internal 
            ID, but via a global identifier that never changes after it has been 
            published. Of course, this sounds like the DOIs, but these are 
            extremely coarse grained and very static. The idea is to attach 
            identifiers to the low-level entities and provide solutions to build 
            up a hierarchical ID system (virtual collections) to account for the 
            various layers used in our data. Such persistent identifiers should 
            then be placed prominently in any user interface dealing with 
            managed data. The important thing is: If data is updated, we don't 
            update the data behind identifier x, but assign a new identifier y 
            and create a typed link between these two (which may be the most 
            challenging part) and perhaps put a small annotation on x that this 
            data is depreca<BR></BLOCKQUOTE></BLOCKQUOTE>

            redirect a user consistently to the latest version of a dataset if a
