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:

********* 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.
