This is the first in a series of posts asking for review of specific sections of the Incubator's Group draft final report. Note that at the end of this email there is a section called "Scope of this report" that gives some key definitions of terms. ********* Please forward to appropriate parties and lists ****** The W3C Library Linked Data Incubator Group would like a comments and suggestions on the group's final report. All comments should be sent to the public mailing list: public-lld@w3.org. Posting is allowed to non-subscribers. Because each of these mails contains only a small section of the report, it is advised to view the section in its context: http://www.w3.org/2005/Incubator/lld/wiki/DraftReportWithTransclusion ********* Benefits, Part I *********** Benefits of the Linked Data approach The Linked Data approach offers significant advantages over current practices for creating and delivering library data while providing a natural extension to the collaborative sharing models historically employed by libraries, archives, and museums ("memory institutions"). Linked data is sharable, extensible, and easily re-usable. It supports internationalization of data and user services. These characteristics are inherent in the linked data standards and are supported by the use of web-friendly identifiers for data and concepts. Resources can be described in collaboration with other libraries, and linked to data contributed by other communities or even individuals. Like the linking that takes place today between web documents, linked data allows anyone to contribute their unique expertise so that it can be reused and recombined with the expertise of others. The use of identifiers ensures that the diverse descriptions are all talking about the same thing. Through rich linkages with complementary data from trusted sources, libraries can increase the value of their own data beyond the sum of its sources taken individually, as in the story of the stone soup, where the hungry travellers' boiling a pot of stones attracted from the locals enough curiosity, and small contributions of herbs and carrots, to create a nourishing meal. By using globally unique identifiers to designate works, places, people, events, subjects, and other objects or concepts of interest, memory institutions can make trusted metadata descriptions available for common use, allowing resources to be cited across a broad range of data sources. An important aspect of the identifier system is its use of the Domain Name System of the Web. This assures stability and trust in a regulated and well-understood ownership and maintenance context. This is fully compatible with the long-term mandate of memory institutions. Libraries, and memory institutions generally, are thus in a unique position to provide the metadata for resources of long-term cultural importance as data on the Web. Library authority data for names and subjects will help reduce redundancy of bibliographic descriptions on the Web by clearly identifying key entities that are shared across linked data. This will also aid in the reduction of redundancy of metadata representing library holdings. ********* Some Definitions ************** "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. As discussed [elsewhere in the report] in more detail below, this report pragmatically distinguishes three types of library data based on their typical use: datasets, element sets, and value vocabularies. 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. -- Karen Coyle kcoyle@kcoyle.net http://kcoyle.net ph: 1-510-540-7596 m: 1-510-435-8234 skype: kcoylenet
