Could you please read and give feedback on the "Scope of this report" section? As we discussed Thursday, it would be very helpful to get feedback from the entire group on this one!

I've pasted the text below; it's also at
Please pardon the non-plain-text; this hasmore than the usual amount of wiki formatting.

Let us know what you think -- or of course, feel free to edit it!


"Library Linked Data": Scope of this report

The scope of this report -- "library linked data" -- can be understood as follows:
Library. The word "library" (analogously to "archive" and "museum") refers to three distinct but related concepts: a collection, a place where the collection is located, and an agent which curates the collection and administers the location. Collections may be public or private, large or small, and are not limited to any particular types of resources.
Library data. "Library data" refers to any type of digital information produced or curated by libraries that describes resources or aids their discovery. Data used primarily for library-management purposes is generally out of scope. This report pragmatically distinguishes three types of library data based on their typical use:
Datasets. A dataset is a collection of structured descriptions of "things" such as books, articles, and sound recordings, often in the form of a catalog or of metadata records.
Element sets. A element set, metadata element set, is a set of elements (also called properties or attributes) and classes (entity types) used to describe the items of datasets. Element sets in the sense of this report may be RDF vocabularies, schemas, or ontologies.
Value vocabularies. A value vocabulary is a set of concepts -- e.g., topics, art styles, and authors -- associated with elements as values. Examples include thesauri, code lists, classification schemes, subject headings, controlled vocabularies, and other such knowledge organization schemes.
As an example of the pragmatic nature of these distinctions, note that an authority file, which could be seen as a dataset (providing contextual information about author names), would be considered in this report a value vocabulary because of its typical use in descriptive metadata.
Linked Data. "Linked Data" (LD) refers to data published in accordance with principles designed to facilitate linkages among datasets, element sets, and value vocabularies. Linked Data uses Web addresses (URIs) as globally unique identifiers for dataset items, elements, and value concepts, analogously to the library world's identifiers for authority control. Linked Data defines relationships between things; these relationships can be used for navigating between, or integrating, complementary sources of information.
Library Linked Data. "Library Linked Data" (LLD) is any type of library data that is either natively maintained, or merely exposed, in the form of RDF triples, thus facilitating linking.
