Amsterdam’s LI-MA announces a new cataloguing system that accounts for the complexity of media artworks that confounds traditional museum databases. The Four Level Artwork (FLA) model breaks works down to the artist’s core idea, different iterations of the concept, how the work is technically realized, and the files or objects in a collection. Bas van Koolwijk’s TST (2000) demonstrates FLA: one conceptual work becomes two artistic versions, each with two display formats, and specific tapes in LI-MA’s vault.
