Introduction

Collections and collection-level description

The term "collection" can be applied to any aggregation of physical or digital items. Those items may be of any type, so examples might include aggregations of natural objects, created objects, "born-digital" items, digital surrogates of physical items, and the catalogues of such collections (as aggregations of metadata records). The criteria for aggregation may vary: e.g. by location, by type or form of the items, by provenance of the items, by source or ownership, and so on. Collections may contain any number of items and may have varying levels of permanence.

A "collection-level description" provides a description of the collection as a unit: the resource described by a collection-level description is the collection, rather than the individual items within that collection.

Collection-level description enables a collection provider to

• disclose information about the content and availability of collections to users where item-level metadata does not exist or is not available, or where the provision of item-level detail is not required or appropriate

It enables a user to

• discover and locate collections of interest
• select collections to explore on the basis of a summary description
• compare collections as broadly similar objects, even where items (and/or item-level metadata) are heterogeneous
• understand conditions of access and use
• interpret collections (and items within collections)

Increasingly, many of these functions - notably the discovery, location, selection and comparison of collections - are being carried out by software acting on behalf of a human user, perhaps in accordance with user preferences or with parameters describing the scope of a particular service.

The Dublin Core Collection Description Application Profile (DC CD AP)

A DC application profile specifies which properties are used within a metadata application, and how those properties have been constrained or adapted for the purposes of that application. The DC CD AP specifies how properties from the Dublin Core metadata vocabularies (in association with properties from some other standard vocabularies) may be used for the creation of a collection-level description.

The DC CD AP is intended to provide a means of creating simple collection-level descriptions suitable for a broad range of collections. It is designed primarily to support the discovery and selection of collections, though it may be used to support other functions such as collection management too. It is not intended to describe every possible characteristic of every type of collection.

Also, it provides properties to describe the relationships between a collection and a number of other resources, notably the service that provides access to a collection, and some agents related to the collection. It is quite likely that an application will use metadata descriptions of those related resources as well as the collection, but the description of those resources is outside the scope of this document.

The DC CD AP is independent of any particular syntax for representing descriptions. Separate guidelines will describe how descriptions conforming to the DC CD AP may be represented using the conventions recommended by DCMI for expressing DC metadata using the Resource Description Framework (RDF) and using the Extensible Markup Language (XML).

Functional Requirements of the DC CD AP

The aim is that the DC CD AP should support:

• the discovery of collections of potential interest using some common access points
• the identification of a known collection
• the selection of one or more collections from amongst a number of discovered collections
• the identification of the location of the collection
• the identification of the services that provide access to the collection

Data Model

The DC CD AP is based on a data model which is derived from that described in An Analytical Model of Collections and their Catalogues [1]. It differs from that model in adding a new entity type, Service.

In the Analytic Model relationships may carry attributes; in the DC CD AP, relationships are represented as simple properties and do not themselves carry attributes, so some of the expressivity of the model is lost in the metadata schema.

This version of the DC CD AP describes the use of properties to represent attributes of the collection and relationships between the collection and other entities. It does not describe how to represent properties of other entities in the model.
