If you are developing a new publishing platform, or have control over how publishing platform features are designed or implemented, use existing standards to guide decisions. For example, there are standards for bibliographic data (e.g. ONIX, Dublin Core), full-text data (e.g. TEI, EPUB), annotations (e.g. W3C’s Web Annotation Data Model), persistent identifiers (e.g. DOIs, Handles, ARK IDs), citations (e.g. MLA, BibTeX), metrics (e.g. COUNTER), accessibility (e.g. W3C’s Web Content Accessibility Guidelines) and more. Preservation workflows scale best when working with common standards.
