7 TWG Charge Metadata, persistent identifiers, granularity Citing, linking to and from, references within Archiving, preservation, migration Packaging, exchange, delivery Accessibility

8 Metadata: Basics Article being supplemented (main article) Function: integral, additional, related (?) Descriptive metadata IDs, contributors, title, language, summary, subject descriptors, rights/permissions, funding, accessibility, etc. Physical metadata File name, format, size, date, mimetype/subtype, created with, application requirements, validity check, ext. link, etc.

9 Metadata: Complexities Heterogeneity: a single supplemental ZIP, TAR, or PDF may contain multiple files. Some may be Integral; others, Additional. Content granularity: assign metadata to supplemental material as a whole? Individual objects? Object groups? All? Relationship granularity: identify relationship to the article as a whole or to its individual components (to Table 4, to Fig. 7)? Equivalency relationship: a single chemical structure or a protein may have multiple representations, e.g., a table, a figure, and an interactive application. One may be primary; each may have different preservation requirements.
