Introduction Technical appraisal is the process of
determining the (on-going) feasibility of preserving the digital objects◦ Maintenance in a reusable form ◦ Takes into account obsolescence of software,
formats etc.
Aim to produce a general purpose tool◦ Conference demonstrator is for digital video

Digital video art at Tate
Circa 500 video artworks, increasing at c. 50 works per year
Limited (though increasing) and familiar technologies. In-house experience and regular use.
Production environment similar to quality checking environment.
Existing network of experts Common technologies within the communities of Practice

FeaturesDemonstrates use of:
External data sources to estimate risk (e.g. obsolescence, hardware failure)
◦ Search engines◦ Software repositories◦ Wikipedia
Ecosystem models◦ PERICLES Digital Video Art (DVA) (extended) ontology and
Linked Resource Model (LRM)◦ Captures dependencies between artwork components ◦ Represents expert knowledge about video playback

Functionality Collection and object level risk assessment for complex
digital objects◦ Support proximity estimation and confidence estimates
Component level risk analysis ◦ Identify high-risk components across collections◦ Provide graphical views
Object-level risk analysis◦ Presents risks to individual components in an object◦ Determine potential recoverability actions
