Metadata for vector images is discussed in detail in The Significant Properties of Vector Images (Coyne et al 2007), from which the elements below are taken, and on the JISC Digital Media page discussing ‘Metadata and Digital Images’. The elements below are largely Dublin Core[2] elements which are most usefully generated by the image creator. In addition, some technical elements are suggested (only a subset of those presented in The Significant Properties of Vector Images) which may be optionally completed by the data creator.

Element	Description
Identifier	A unique identifier for the image, usually the filename
Title / Caption	The title of the image or a suitable caption
Description/Purpose	Description of the image
Creator	Name of image creator
Date	Creation date
Rights	Details of copyright or other rights and holder details
Keywords	Keywords e.g. period, site or feature terms. Use suitable thesauri where they exist
Provenance/Relationship to other documents	Description of where the image originated and how (if relevant) it is related to other files
Conventions	If applicable and not contained within the document, an explanation of all conventions used (colours, layers, line styles, line weights, etc.)

Additional basic technical metadata

File Format and Version	e.g. SVG 1.1
