Expressing Needs of Digital Audio-Visual Applications in Different Communities of Practice for Long-Term Preservation

Lack of awareness on preservation tools and applications is a big issue today. To solve it European Commission has initiated research project, Presto4U that aimed to enable semi-automatic matching of preservation tools with audio-visual needs. To express the audio-visual needs formally it has mapped a knowledge schema. The knowledge schema was first cut and needed evaluation in terms of its ability to represent the Needs of different communities of practice, classes, their association and ability to represent requirements of Audio-visual community through properties of its classes. This evaluative study is conducted through Qualitative research approach using Interview and Questionnaire. Open Archival Information System reference model is used as theoretical framework. Fourteen members from Europe of three communities of practice have provided their needs for analysis. Data was analysed through six stages. The study found that knowledge schema is useful to express the needs of communities of practice but collected data should easily fit into the structure of knowledge schema.
