What is Metadata?
What is Metadata?
Technical metadata – hardware, software, file formats, resolution, size
Preservation metadata – provenance, authenticity, preservation actions, responsibility (eg. PREMIS)
Structural metadata – physical/logical structure of digital resources (eg. METS)
Descriptive metadata – describes the digital resource; catalogue records/finding aids
International Standard Archival Description (General) or ISAD (G) is an international standard which provides guidelines for creating the content of an archival description.
It promotes the creation of consistent and appropriate descriptions, aiding the retrieval and exchange of information, and the integration of descriptions into a unified information system.
ISAD (G) sets out a list of elements which are considered necessary for an archival description, and rules that should be followed when writing a description. ISAD (G) identifies and describes what kind of information should be included in an archival description and whether this description is in written, printed, or electronic form.

Metadata standards
DRI metadata guidelines
• Dublin core and Qualified Dublin Core
• MODS
• EAD
• MARC
Why use standard metadata?
Using standardised descriptive metadata means adhering to the best practices in your domain.
Standardised metadata allows you to control how records are described within your organisation too.
Enforcing standards allows greater consistency and therefore searchability of your records.
Metadata sharing and interoperability is only possible when a standard is used.
Cost saving – the schema and its usage guidelines have been developed thus saving time and effort
Access to help and advice – a standard is likely to have a community of users, which means there will access to help and advice about how best to use the standard
Usability – users are likely to be familiar with a standard and its terminology, thus they can more quickly and easily use your collection
Sustainability – use of common standards will make it easier to pass your collection on to someone else to look after if you ever need to From the JISC metadata infokit,
