The file plug-ins would not use these functions via the PDB because they could use the library directly. However, it is still useful to have these functions exported to the PDB so that they can be used by scripts. For example, if you want to have a script that automatically attaches a Creative Commons license to a file, it would only have to call something like this: gimp-metadata-set-scalar (image, "xmpRights", "marked", "true") gimp-metadata-set-scalar (image, "cc", "license", "http://creativecommons.org/licenses/whatever";) That covers the "why". Regarding the "how", it depends... My long-term goal is to move the metadata viewer/editor into the core (like other info dialogs and so on) because it would be the only way to ensure that it reflects the current state of the metadata while the image is being edited. This would solve some of the annoying concurrency problems: if you open the metadata editor (currently a plug-in), and save the image while the editor is open, then some changes to the metadata are lost because the parasite is modified by the file plug-in but the editor does not know it. I think that I mentioned this before or during the last GIMPCon. So if/when the metadata viewer/editor is in the core, then it makes sense for the core to export some of these functions to the PDB. But I am not planning on migrating the editor to the core right now. In the meantime, it may be better for the editor (the GUI part) to remain as a plug-in and then it would make sense for it to export these functions to the PDB. But even if these functions are temporarily exported by a plug-in, I think that it would be better to name them "gimp-metadata-*" in order to reflect the intent to move them into the core later, and to avoid breaking scripts that could start using them in the meantime. -Raphaël _______________________________________________ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
