Abstract

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.

Digital Preservation

The precious digital information stored in hard discs of research organisations throughout the world is becoming inaccessible rapidly. Moreover analog information is also digitized on the same pace. So it is necessary to make this information available in accessible and usable form for future generations. According to an International Data Corporation study for 2007, 264 exabytes of data were created. In future this data would grow at 57% annual growth rate, faster than expected growth rate of storage capacity. (Jelitto, 2010) So, most of this data would be preserved. Digital preservation should address changes that certainly occur in hardware or software, in organisational or legal environments. It must contain metadata or representation information for interpretation of original information and easy retrieval of information.

ALA (2007, p. 1) defines Digital preservation as combination of policies, strategies and actions that ensure access to digital content over time. The goal of digital preservation is to preserve materials resulting from digital reformatting, and particularly information that is born-digital with no analog counterpart. Because of the relatively short lifecycle of digital information, preservation is an ongoing process. (Tessella, 2013) It is necessary to know the importance of preservation of information. There are three categories for which we need to preserve data. First to maintain Regulations i.e. the time retention set by national and international regulatory bodies to keep information. Second, Legal defence that includes defend or prosecute against any legal action. Final, Knowledge re-uses that deals with preserving the information for future researchers. (Tilbury, 2010)
