Which machine-readable TDM reservation mechanisms exist, at which versions, and what do their primary texts say about legal status?
Four mechanisms are read in primary text. EU Directive 2019/790 Art. 4(3) conditions the general TDM exception on no express reservation 'such as machine-readable means' for online content (recital 18: including metadata and website terms). W3C TDMRep (Final CG Report 2024-05-10) describes itself as a technical answer to Art. 4: a tdm-reservation flag and policy URL via a well-known file, HTTP headers (which supersede the file), HTML meta and EPUB/PDF XMP. IPTC's plus:DataMining (2023.1) warns that laws may overrule it and that absence is not permission. CAWG training-mining 1.1 uses allowed/notAllowed/constrained per use, with constrained treated as notAllowed absent more information. No text maps one to another, and no legal conclusion is drawn.
