Hi Rosemarie, interesting initiative, some comments inline - Rosemarie Haberecht wrote: > Requirements for Libre-Office are: > - internal RDF Metadata tag logic/visualization in layout > Yep, that's missing sadly - Dennis already referenced tdf#30709, though perhaps would be good to specify a bit more what kind of UI you actually need here (if you have mockups like for the other features?). Depending on whether that's what the submitter of tdf#30709 meant, those UX mockups/examples can go to that enhancement task, or rather need a new bug report. > - a status bar, a task pane and a customized menu, as well as key > combinations > Ilmari answered that - reasonably straight-forward to implement that as part of a LibreOffice extension (who can additionally customise/modify UI). > - a status bar: arranging buttons > https://mobileguides.de/downloads/libreOffice/Statusbar.png > Can't easily tweak the existing status bar, but if adding an extra statusbar (essentially just a toolbar by all intends and purposes) would cut it - that's also quickly doable. > - a task pane: arranging GUI for the visualization of additional attributes > for a metadata object > https://mobileguides.de/downloads/libreOffice/Taskpane.png > LibreOffice supports extending the sidebar panel from Extension code, you have comparatively large screen real estate there, and the stuff can be context-sensitive. If you need pointers how to implement custom sidebar content, let us know. One rather complex example of what's doable is the WollMux extension, code is here: https://github.com/WollMux/wollmux-core > - customized menus for quick functions > See above, that's easily doable. > - Key combinations for ingest and tagging functions > Same. > Now we ask ourselves the question which parts of the requirement can be done > where? > > Kernel - visualization of the tags, interface to access the metadata > objects > Yeah, let's call it core - that's indeed changes that need doing inside Writer c++ code. RDF metadata API is already available though. > Plugin - Taskpane extension? > Extension - Addon when is what used, is it the same? > Macros - Basic internal macro functions controllable via menu > The above would be subsumed under one or more LibreOffice extensions (see link from Ilmari for how to get started there). Implementation language is certainly a matter of taste & personal preference; from a tech stack perspective, Basic is probably the worst possible choice though - not the least because there's very little support libraries available. Personally, I would use either Java or Python for extension - they're both cross-platform, have a vast ecosystem of tools & libraries, and feature 1st-level support in LibreOffice. Python has the slight upside in that it's built-in for _every_ LibreOffice installation; for Java, an additional JRE install is usually required. Hope that helps, all the best, -- Thorsten
