9. IVOA InterOpOct20056-7 Oct 2005: Madrid Sheet Name Designation A VOTable file will be transformed into several sheets, sometime more then ten, depending on the VOTable structure. Each sheet is designed a name using ID or name attribute of its originated ELEMENT. If neither ID or name is available, TABLE, RESOURCE, VOTABLE will be used. TableData level VOTID_RESID_TABID_TYPE: VOTABLE_yCat_2246_II_246_out_DATA RESORCE level VOTID_RESID_TYPE: VOTABLE_yCat_2246_Other VOTABLE level VOTID_TYPE: VOTABLE_INFO TYPE values include: DATA, FIELDS, INFO, PARAM, GROUP, Other

10. IVOA InterOpOct20056-7 Oct 2005: Madrid Non-supported VOTable features Only "TABLEDATA" data content is supported. "FITS" and "BINARY" serializations are NOT supported. Not supported VOTable elements and attributes: Recursive "RESOURCE" elements Recursive "GROUP" elements "VALUES" elements for "FIELD" and "PARAM" elements All attributes except "href" of "LINK" elements "encoding" attribute of "TD" elements It is almost impossible to losslessly map 3-D tree XML file onto a 2-D plain spreadsheet.

11. IVOA InterOpOct20056-7 Oct 2005: Madrid Some thoughts about Bruno Rinos comments First, thank Bruno very much for his detailed test and report! A bug-fix version is under preparing. Selected comments: create a note (tooltip) for the "header" cells on the data spreadsheet Good Idea, note is supported by OpenDocument format. New version will support this. Take advantage of the LINK element... create links on corresponding data cells LINK is seldom used by VOTable creators, well-formed VOTables are not very common. We need think over about this feature. Suggestion for VOTable creators: create well-formed VOTable data and files following the VOTable schema. Known numeric data shouldn't be loaded as text. String is the most accurate type, will not loss any precision. OpenOffice or Excel has its own method to cope with numeric types, sometime the results are not you wanted. More suggestions are welcome on the issue...... provide sample formulas and macros Is it out of the scope of the VOFilter? Speak frankly, I dont understand well on how to use these functions in OpenOffice. I will try when I have time. LINK http://ivoa.net/forum/votable/0509/0775.htm
