We have found 2 software records in our database eligible for .xmp to .pdf file format conversion.
XMP format from Photoshop Lightroom (Adobe Extensible Metadata Platform) actually does not contain any graphics data, just metadata, thus direct export to PDF format does not make sense. You can actually find these along graphics files (JPEGs, TIFFs) that lack the capacity to save particular metadata and it is these graphics you have to export to PDF.
All this means that you will need both the .xmp and the referenced graphics files for successful export of this kind and of course access to Photoshop Lightroom.
