To use a bit of TCS in some other schema, you would import the element types and extend them. But TCS mostly does not expose its element types as named types that can be referenced externally - it's all done inline. This means that the only place a TCS "ScientificName" or "Rank" element can appear is somewhere inside a TCS DataSet element.

The "real" type needs to go in the ProviderSpecificData section - miles away (in the document) from what is supposed to be the primary place where the relationship is described. It's ugly. Furthermore, some of our relationships don't really match the TCS ones at all well - to the point that using a TCS type would be misleading. The TCS enumeration does not have a "other" value, so there was a bit of an impasse.</span></span><o:p></o:p></p></div></div><div><div><p class=MsoNormal> <o:p></o:p></p></div></div><div><div><p class=MsoNormal><span class=apple-style-span><span style='font-size:9.0pt'>In any event, we were looking at either putting some relationships in the TCS array, and some in the PSD array, or putting corresponding arrays in each. Of course, in the provider specific data section we cannot use any of the TCS elements, because the element types are not exposed and can only appear in a TCS DataSet at the correct spot. It just got to the point where the ProviderSpecificData section was bigger and more interesting than the TCS, so we broke it out into a separate XML document (which was bundles with the TCS using an ibis:documents wrapper), at which point we couldn't help but ask "Can some one explain again why we are trying to do this?".

If you have any valid XML document with any TCS element, then you know that it will be enclosed in a DataSet element and come bundled with enough context to make sense of it. It's a model for shifting around entire, self-contained *sets* of data. Entire taxonomies, sitting as big files on a disk (or in an xml store). But our service layer serves up fragments - one or several taxa in response to a request, and TCS turned out to not be a good model for what we do. The history of trying to use it has left us with a legacy of having multiple relationship-type fields (relationship "description" and relationship "category") whose product does not form a sensible set of values.<o:p></o:p></p></div></div><div><div><p class=MsoNormal> <o:p></o:p></p></div></div><div><div><p class=MsoNormal>What we have now is a site-specific schema that captures and exposes the data we have. Admittedly, this means that the grand goal we are all trying to accomplish - a consistent worldwide net of data - is not as far down the track as we were hoping to go. It means that the problem of working out how data set 1 matches data set 2 is pushed off onto aggregators, a job that is in general impossible for an aggregator to accomplish. If we could have fitted our data into TCS, if everyone else could also have done so, then that would have been wonderful. We were reluctant to abandon it, but to get our data out the door we eventually did.<o:p></o:p></p></div></div><div><div><p class=MsoNormal> <o:p></o:p></p></div></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><div><div><p class=MsoNormal>On 02/11/2012, at 9:41 AM, <<a href="mailto:Tony.Rees@csiro.au">Tony.Rees@csiro.au</a>> <<a href="mailto:Tony.Rees@csiro.au">Tony.Rees@csiro.au</a>> wrote:<o:p></o:p></p></div></div><div><div><p class=MsoNormal> <o:p></o:p></p></div></div><div><div><p class=MsoNormal> <o:p></o:p></p></div></div><div><p class=MsoNormal><br><br><br><o:p></o:p></p></div><div><div><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Hi TDWG persons,</span><o:p></o:p></p></div></div><div><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p></div></div><div><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>I am involved in an activity here to set a local standard for storing taxonomic name, identifier and (probably) hierarchy information in metadata records using our profile of ISO 19115 for the latter, and the question will come up as to whether to use elements from TCS, DwC, EML, NCBII extension to ISO 19115, or other.

It's legitimate (from a machine point of view) for a site to create their own terms. However, this does mean that the world becomes fragmented into a number of site-specific vocabularies that cannot be machine-reasoned over. The underlying reason for this is that that is in fact the way the world actually is at the moment, and there's not a lot of help for it.</span><o:p></o:p></p></div></div></div><div><div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Helvetica","sans-serif";color:black'> </span><o:p></o:p></p></div></div></div><div><div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Helvetica","sans-serif"'>-------------------------------------------------------------</span><o:p></o:p></p></div></div></div><div><div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Helvetica","sans-serif";color:black'> </span><o:p></o:p></p></div></div></div><div><div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Helvetica","sans-serif";color:black'>There are two or three approaches to using a standard vocabulary when your own data does not quite match it.</span><o:p></o:p></p></div></div></div><div><div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Helvetica","sans-serif";color:black'> </span><o:p></o:p></p></div></div></div><div><div><div><p class=MsoNormal><span style='font-size:13.5pt;font-family:"Helvetica","sans-serif";color:black'>You can use the standard term that is *closest in meaning* to your own term.

It's a never-ending job. It might be an idea to have the design guideline that no enumeration class defined by the vocabulary shall have more than 10 values.
