Plastics are chemically unstable in the long term and their lifespan can only be prolonged by well-planned conservation practices. Light is especially harmful. Some plastics are more chemically stable than others and as plastic boxes and sleeves are commonly used for storage it is important to choose the right materials. Plastics such as PVC rapidly deteriorate and, in the process, give off chemicals that can react with other materials, causing damage. Storage media for photographs, photographic films and audio, video and computer all use plastic materials as a base. Archiving the digital data held on electronic storage media requires special treatment (see B.10.7).

The use of XML for long-term archiving of digital data is also an objective of the FISH Interoperability Toolkit project (see B.6.4). The MIDAS XML schema which lie at the heart of the Toolkit, have been developed in line with recommendations of the World Wide Web consortium. They provide a suitable XML format for the storage of text data output from typical Historic Environment Records. No special software is required to access XML files: they can be read with standard PC accessories such as Notepad, Wordpad or recent versions of Internet Explorer.

A major archival function is the categorisation and description of datasets. Such metadata (see B. 9.3) is used to describe both the data format/medium and the content of a resource. The former aids preservation strategies while the latter helps in locating and accessing a desired resource. Of late much research has gone into agreeing metadata standards, such as the Dublin Core, in order to promote accessibility and to facilitate the use of distributed resources.
