What is Metadata Container

Chapter 19
Handbook of Research on Digital Libraries: Design, Development, and Impact
It is the unit for aggregating the typed metadata sets, which are known as packages. A container may be either transient or persistent. In its transient form, it exists as a transport object between and among repositories, clients, and agents. In its persistent form, it exists as a first-class object in the information infrastructure. That is, it is stored on one or more servers and is accessible from these servers using a globally accessible identifier (URI). We note that a container may also be wrapped within another object (i.e., one that is a wrapper for both data and metadata). In this case the “wrapper” object will have a URI rather than the metadata container itself.

Abstract
his chapter presents basic guidelines for maintaining digital cultural collections in order for them to be interoperable and easily retrievable from users. The requirements of cultural material are discussed and it is shown how in combination with the adequate metadata schema policy a digital cultural collection can cover the various needs for learning and retrieving information. The authors emphasize the fact that various metadata schemas are used for describing cultural collections and that this leads to problems for interoperability. It is analyzed that while designing a digital collection, the internal structure of material must be followed and the metadata model must cover specific needs; furthermore, a data preservation policy is a considerable issue in the digital era.
