LibreOffice's File > Properties / Word's File > Info, reachable from both chromes' file menus. ODF writes them into the meta.xml odf-kit already emits (one meta:keyword each, generator EdenText); DOCX passes them to the package's core properties. Both importers read them back, and LibreOffice shows every field from either format.
