Anu’s entry for weeks 11-22 July 2011

ak19. Friday, July 22nd, 2011.
  • Week starting 11 July: Closed ticket 770 to do with multiple pieces of metadata for the same metadata name in GS3. GS3 was previously not consulting the mdoffset field in the index database to work out which of multiple assigned metadata values to display for a particular metadata field. When browsing on that metadata field, it used to display only the first each time, but now displays all values in turn.
  • For the rest of that week and the start of the week thereafter, worked on some items discovered by John Rose and Luigi. They found a bug in the GS2 OAI server that manifested when a GS2 client tried to download docs from it over OAI. The bug had to do with an incorrect URL being generated for the dc.Resource Identifier field. They also requested a minor improvement to the button layout in GLI’s OAI download panel and needed some clarifications on the GS2 OAI server’s behaviour.
  • Continuing on in the week of 18 July: On GLI startup, an information dialog box will show up if the user does not have the PDFBox extension installed (telling them how to get it if they want newer PDF versions processed). A dialog will also appear on startup if the user’s collect home was set to be somewhere outside its default location inside the GS2 installation.
  • In implementing the last, a bug was discovered that had been introduced when implementing the reset-gsdlhome target of the gsicontrol script. The bug interfered with the proper behaviour of setting and loading a custom collecthome when using GLI. It’s now been fixed in such a manner that there’s the added advantage that the intensive operations of the reset-gsdlhome task will not be carried out anymore each time the GS2-server is launched. Instead, the relocation-specific operations are only performed when GSDLHOME has in fact changed since the previous time the GS2-server was launched.
  • The pdfbox-app.jar executable file was changed again: it was returned to being the plain, official 1.5.0 release, without the Greenstone-specific changes regarding the line-separator that had thereafter been committed. Instead, the line.separator is now set as a command-line property when launching the pdfbox-app.jar, as suggested by Dr. Bainbridge, since it was no more than a Java System property that needed to be adjusted for GS’ customisation of PDFBox anyway.
  • Changes have been made to modelcol’s config.cfg (and related changes in runtime-src) to deal with embedded metadata, so that it will now handle the “ex.” prefix of metadata already qualified by a set name, such as ex.dc.something. Further changes were made to runtime-src’s code to not always remove the ex. prefix, since this should be retained for embedded metadata. The handling of embedded metadata by the DSpacePlugin was also slightly modified so that DC metadata in the dublin_core.xml files of DSpace documents get prefixed with “ex.”. This allows these metadata fields to be visible in GLI, while yet being unmodifiable, as they are still extracted (ex) metadata.
  • Tried to reproduce some issues noticed by members of the mailing list.
