Balancing the need for accurate metadata to manage, find and use your information against the issues inherent in getting that metadata applied is tricky. The key is to recognise how many metadata values can realistically be captured for your content, and whether this can be done automatically (for example via templates or auto categorisation software), or whether the tags have to be added manually.
Of course metadata can be applied not just at the document level, but also at other levels of granularity, from whole collections to a single paragraph, image or tweet, and different types and formats of content need different metadata elements (fields).
Part of the process is also to identify sets of controlled vocabularies which would support the metadata model. It may also result in the building of a fully-featured taxonomy or ontology to tag the content and ultimately deliver a richer search experience to your users.
Metataxis has devised metadata models, taxonomies and ontologies for government, NHS, third sector and commercial clients. We can advise on what the metadata should be, and what the most efficient ways of capturing it will be. If required, we can even provide people to do the tagging for you in order to take the burden off in-house staff.
Metataxis provides public and in-house training courses in metadata, and also in taxonomy, thesaurus and ontology development.
