it's time to stop thinking and start linking

2. Data

4. In Silos

22. Silos of Silos

32. Silos of Strings

41. Future of
Bibliographic
Control

42. cannot be accomplished by
matching strings

43. cannot be accomplished alone

44. “Until very recently, bibliographic control has been an
artisan activity, as there was no alternative for providing
access except to transcribe, by hand, data from the
objects being described. Now, however, publishers and
vendors are working in an electronic environment, and
print material generally originates in electronic format.
...Despite the fact that descriptive metadata are being
created in other venues, libraries have so far taken
minimal advantage of them.
Given the explosion of material requiring some level of
bibliographic control, the model of item-by-item full manual
transcription can no longer be sustained. Libraries must
find ways to make use of the data created by others in the
supply chain, including data that can be derived from
algorithmic analyses of digital materials.”
On the Record: Report of the Library of Congress Working Group on the Future
of Bibliographic Control

45. RDA

46. RDA
• Based on FRBR, FRAD, FRSAD
• ~375 metadata elements
• 400+ relationships between FRBR
entities
• specification is not free

48. Data

50. Wikipedia

56. Also Silos

57. Silos with data
that could
possibly be used
for:

58. Biographies

59. Reviews

60. Track listings

61. Cast/crew credits

62. Awards

63. Professional Relationships

64. Families

65. If we can figure
out what we’re
talking about

69. This won’t work
with just
matching strings

70. Linked Data

71. Four Rules
1. Use URIs as names for things
2. Use HTTP URIs so that people can look
up those names.
3. When someone looks up a URI, provide
useful information, using the standards
(RDF, SPARQL)
4. Include links to other URIs. so that they
can discover more things.
http://www.w3.org/DesignIssues/LinkedData.html

72. 5 minute (!!!)
intro to RDF

73. Data model, not a
serialization
format

74. A Triple

75. URIs to identify

76. Relationships

77. Graph

78. Cloud

79. Vocabularies

80. Examples
• Dublin Core
• FOAF
• SKOS
• OWL
• BIBO

101. And those other

106. Putting it all
together

116. Doing what we
do best

117. Identifying things

118. 5.7 million NACO

119. 1.3 million

121. When we know
what we’re
talking about, all

122. Let’s start
identifying.
