robin fay @georgiawebgurl 2013
Objectives
By the end of this session, you’ll
• Have an understanding of the basic principles and
terminology of the
– Semantic Web
– Linked data
– Library data in semantic web space
• BIBFRAME
• RDA
• FRBR
robin fay @georgiawebgurl 2013
The web as we know it (and
think of it) links together
documents
(html, pdf, dynamic
documents created from
databases, etc.)
robin fay @georgiawebgurl 2013
In brief:
Types of metadata:
Descriptive
Structural
Administrative
• Many forms of metadata include elements of each of these;
however it is dependent upon the schema.
• A schema is a set of rules covering the elements and
requirements for coding. Examples of common schemas in the
library world include Dublin Core, TEI, EAD, and others. Examples
of schemas in the semantic web include Dublin Core, FOAF
(Friend of a Friend), and many others.
robin fay @georgiawebgurl 2013
•Much of library metadata is highly structured and done by trained
professionals. In the library world, MARC has been a long term
standard. While it can be rigid, its structural nature can makes it
easier to crosswalk and harvest into other databases.
•SEO (Search Engine Optimization) is a common term in the web
world; these experts assign descriptive, administrative (usually
copyright) to websites; their goal is generally higher search
results. Given that search engine algorithms change regularly, SEO
is a highly dynamic field, which can lead to inconsistencies in
metadata application, making it harder for databases and search
engines to harvest.
•In a nutshell, most library metadata has rules and standards;
metadata in the web world is often (but not always) more flexible.
The Semantic Web will need to manage (and make sense!) of all of
these types of metadata.
robin fay @georgiawebgurl 2013
•At its core, the semantic web comprises:
oa set of design principles,
ocollaborative working groups,
oand a variety of enabling technologies.
•Some elements of the semantic web are expressed as
prospective future possibilities that are yet to be
implemented or realized
AND
•Other elements of the semantic web are expressed in
formal specifications -- (wikipedia, 2009)

•Semantic web and web metadata is frequently from outside
of the library community – working in parallel or sometimes,
at odds.
•Metadata in libraries encompasses a wide variety; one of the
most common metadata schemas is MARC.
•MARC is formatted using ISBD punctuation; the content of
what goes into a record is controlled by our cataloging rules
(such as RDA). RDA can be applied using different metadata
schemas – although for now, many libraries are still in a
MARC based world.

•RDF = Resource Description
Framework
•RDFS = Resource Description
Framework Schema
•OWL = Web Ontology
Language
•URI = Uniform Resource
Identifier - think unique
number , URLs
Many terms associated with the Semantic Web are used
or based upon information architecture, database,
information science, and library science fields –
controlled vocabularies, structural elements, etc.
robin fay @georgiawebgurl 2013
RDF = Resource Description Framework
• is a general-purpose language for representing information in the
Web (a metadata data model)
• is a W3C specification
• is a conceptual description
• is based upon making statements about web resources (triplets)
• More or less : XML
• We can express RDA in RDF
• Think sentence structure :
• subject – predicate(verb)-object
• My dog eats dogfood.
robin fay @georgiawebgurl 2013
So, we have the framework, but how do we apply it?
RDFS = Resource Description Framework Schema
oA schema is
 outline: a schematic or preliminary plan
 A structure described in a formal language supported by
the database management system ; in a relational database
[such as MySQL), the schema defines the tables, the fields in
each table, and the relationships between fields and tables.
 a description of the structure and rules a document must
satisfy for an XML document type
 http://tinyurl.com/yj442vr (define: schema -- google)
 Dublin Core is a schema
robin fay @georgiawebgurl 2013
Very Simple
Dublin Core in
RDF
We can combine schemas
robin fay @georgiawebgurl 2013
OWL = Web Ontology
Language
•invented to link ontologies which
are classification systems
•Attempts to define objects and their
relationships
•Different “flavors”
•“interpreted as a set of "individuals"
and a set of "property assertions"
which relate these individuals to
each other” (wikipedia 2009)
•Not a requirement
•Sounds familiar to catalogers, right?
robin fay @georgiawebgurl 2013
robin fay @georgiawebgurl 2013
Being that this is data
driven, we can
query, using SPARQL, a
standard query
language.
We’ll talk more about SPARQL later…
robin fay @georgiawebgurl 2013
•Linked data is: “about using the Web to
connect related data that wasn't
previously linked, or using the Web to
lower the barriers to linking data.”
•Think> related, series records, authority
files
•Libraries already link data.
•Projects such as the NYT Linked Open
Data project and the Virtual Authority
File project are resources of controlled
vocabularies.
•Verified and digital identity accounts
such as openID and claimID to
differentiate names
robin fay @georgiawebgurl 2013
• What is linked data and open data
o Linked data is about reusing data
o We already do some linked data in our library
catalogs and even in our daily lives
o The link in a bibliographic record (like an authority
record link) is linking data behavior
o A link that we share to our friends on facebook is
linked data (of sorts)
• Linked data is a link to a record/data/content
that can then be utilized in some way
• Open data is data that available to be used in
some way with no barriers to access (licensing,
etc.) robin fay @georgiawebgurl 2013
Basic principles of linked data
It keeps us from having to re-enter or copy information
– Making our data:
• reusable
• easy to correct (correct one record instead of multiples)
• efficient
• and potentially useful to others
It can build relationships in different ways - allowing us to create
temporary collections (a user could organize their search results in a
way that makes sense to them) or more permanent (collocating ALL
works by a particular author more easily; pulling together photographs
more easily)
robin fay @georgiawebgurl 2013
• Advantages (reusable data, potential to provide
and built relationships, discoverability)
• How library data fits into linked data
o FRBR ( a bibliographic FRAMEWORK which is more
semantic by nature) RDA ( metadata rules which
are not tied to a programming language such as
MARC but can work with semantic web standards
like XML); IRs, and CMS like Drupal which have
semantic web capabilities
• RDA expressed as RDFa
robin fay @georgiawebgurl 2013
The RDF Triple:
conceptual Examples
same as
author of
Predicate/verb
Tim Berners-Lee’s 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
4. Include links to other URIs, so they can discover
more things
URIs = Uniform Resource Identifier
robin fay @georgiawebgurl 2013
What can linked data do for libraries?
• URIs creates methods for classifying that can be used
(linked to!) by others
• Library of Congress has released LCSH as linked data, and
OCLC has a modified version of LCSH called FAST as
linked data
• Linked Data is flexible enough to express entity-
relationship relationships such as FRBR/FRAD
• Different databases (ILS, ERMS, IRs, local databases, etc.)
allowing sharing of data – potentially more consistent
data – allowing for collocation across resources and
allowing users to easily find resources regardless of
source

Intro to the semantic web (for libraries)
How cataloging is changing
: A changing library and WEB landscape
• Automation and new technologies
• The web has changed
• Large scale bibliographic databases
• Cooperative cataloging
• Administrative desire to decrease costs
• Greater variety of media in library collections
(electronic!)
• User expectations and needs
• FRBR is our data model – semantic web friendly!
robin fay @georgiawebgurl 2013
• FRBR will give us a way to group things in different
ways building relationships between data – by WEMI
(Work, Expression, Manifestation, Item)
• WEMI is a hierarchy from abstract to the actual thing
owned by a library (the well… item!)
• Work and Expression can be somewhat conceptual
with lots of discussion going on; however, you can
loosely think of Work as a concept or idea which is
Expressed (think the act of creation; performance)
onto/into a physical format (can be digital) aka a
Manifestation, of which the library has a copy (Item).
robin fay @georgiawebgurl 2013
Entity-Relationship Model
(new way of storing & organizing data)
• Database design model
• Entity - a thing with an identity
– Entities have attributes (characteristics)
• Relationships
– Between different entities at different levels
• Provides for organization of records in database
– “clustering”
• Conceptual model of abstract concepts
robin fay @georgiawebgurl 2013
FRBR and RDA properties element sets
“User Tasks”
How do catalog users
• Find
• Identify
• Select
• Obtain
… the resources they want?
robin fay @georgiawebgurl 2013
Work
A distinct intellectual or artistic creation
Group 1 Entities (WEMI Hierarchy)
Expression
Intellectual or artistic realization of a work
Manifestation
Physical embodiment of an expression of a work
Item
Single exemplar of a manifestation

RDA, FRBR, and MARC
RDA is our metadata rules to describe our content
FRBR is our semantic web friendly data model
Currently we use MARC to format our data but we
need something better
Linked data can be the mechanism – but what
about the actual records?
robin fay @georgiawebgurl 2013
RDA, FRBR, and MARC
• Bibliographic records are structured in MARC (a
programming language). MARC (MAchine Readable
Code) and AACR2 have been working together a long
time which means that compromises and workarounds
have sometimes be made. This will be true for RDA,
too.
• MARC is a mixture of controlled access points (series,
name authority and subject headings + free text (e.g.,
contents notes). This provides flexibility and structure
but> More free text = less precision in searching =
more work for systems to return relevant results

robin fay @georgiawebgurl 2013
• MARC existed before AACR2. MARC was developed in
the 1960s before most digital technology existed –
the web as we know it, ebooks, and Google, did not
exist.
• Most current catalog systems use MARC, but there
are other metadata schemas and programming
languages.
• Although many systems have not fully utilized all of
the fields and functionalities of MARC, it is reaching
the end of its lifespan.
• The next generation (nexgen) systems can not
develop as only MARC based; we need more.
RDA, FRBR, and MARC
robin fay @georgiawebgurl 2013
• Our future systems will probably not use MARC, but some
kind of semantic web friendly schema.
• Currently, the Library of Congress has started a project
called the Bibliographic Framework Transition Initiative
• Why?
• We need something that is more flexible, not flat in file
structure, yet works with a semantic framework.
• We need something that works better with different
metadata schemas.
• This new framework will provide us with enormous
functionality in our catalogs and allow us to fully use RDA.
It will allow us to move forward into the semantic web
world.
RDA, FRBR, and MARC
robin fay @georgiawebgurl 2013
• We have some relationships within our library catalog via the
bibliographic data – bib-holding-item (a way to keep all of the
parts of a particular thing together)
• Bib to authority –series-subject headings (a bib record having
linking field(s) to another record(s))
• Authority records – records not visible to the public, but
provide the linking points to our bib records and guide the user
through variations of the name or title, etc.

Intro to the semantic web (for libraries)

  • 1. Introduction to the Semantic Web Robin Fay @georgiawebgurl robin fay @georgiawebgurl 2013
  • 2. Objectives By the end of this session, you’ll • Have an understanding of the basic principles and terminology of the – Semantic Web – Linked data – Library data in semantic web space • BIBFRAME • RDA • FRBR robin fay @georgiawebgurl 2013
  • 3. The web as we know it (and think of it) links together documents (html, pdf, dynamic documents created from databases, etc.) robin fay @georgiawebgurl 2013
  • 4. In brief: Types of metadata: Descriptive Structural Administrative • Many forms of metadata include elements of each of these; however it is dependent upon the schema. • A schema is a set of rules covering the elements and requirements for coding. Examples of common schemas in the library world include Dublin Core, TEI, EAD, and others. Examples of schemas in the semantic web include Dublin Core, FOAF (Friend of a Friend), and many others. robin fay @georgiawebgurl 2013
  • 5. •Much of library metadata is highly structured and done by trained professionals. In the library world, MARC has been a long term standard. While it can be rigid, its structural nature can makes it easier to crosswalk and harvest into other databases. •SEO (Search Engine Optimization) is a common term in the web world; these experts assign descriptive, administrative (usually copyright) to websites; their goal is generally higher search results. Given that search engine algorithms change regularly, SEO is a highly dynamic field, which can lead to inconsistencies in metadata application, making it harder for databases and search engines to harvest. •In a nutshell, most library metadata has rules and standards; metadata in the web world is often (but not always) more flexible. The Semantic Web will need to manage (and make sense!) of all of these types of metadata. robin fay @georgiawebgurl 2013
  • 6. •At its core, the semantic web comprises: oa set of design principles, ocollaborative working groups, oand a variety of enabling technologies. •Some elements of the semantic web are expressed as prospective future possibilities that are yet to be implemented or realized AND •Other elements of the semantic web are expressed in formal specifications -- (wikipedia, 2009) Robin Fay, robinfay.net 2009/10 robin fay @georgiawebgurl 2013
  • 7. Robin Fay, robinfay.net 2009/10 •Semantic web and web metadata is frequently from outside of the library community – working in parallel or sometimes, at odds. •Metadata in libraries encompasses a wide variety; one of the most common metadata schemas is MARC. •MARC is formatted using ISBD punctuation; the content of what goes into a record is controlled by our cataloging rules (such as RDA). RDA can be applied using different metadata schemas – although for now, many libraries are still in a MARC based world. robin fay @georgiawebgurl 2013
  • 9. •RDF = Resource Description Framework •RDFS = Resource Description Framework Schema •OWL = Web Ontology Language •URI = Uniform Resource Identifier - think unique number , URLs Many terms associated with the Semantic Web are used or based upon information architecture, database, information science, and library science fields – controlled vocabularies, structural elements, etc. robin fay @georgiawebgurl 2013
  • 10. RDF = Resource Description Framework • is a general-purpose language for representing information in the Web (a metadata data model) • is a W3C specification • is a conceptual description • is based upon making statements about web resources (triplets) • More or less : XML • We can express RDA in RDF • Think sentence structure : • subject – predicate(verb)-object • My dog eats dogfood. robin fay @georgiawebgurl 2013
  • 11. So, we have the framework, but how do we apply it? RDFS = Resource Description Framework Schema oA schema is  outline: a schematic or preliminary plan  A structure described in a formal language supported by the database management system ; in a relational database [such as MySQL), the schema defines the tables, the fields in each table, and the relationships between fields and tables.  a description of the structure and rules a document must satisfy for an XML document type  http://tinyurl.com/yj442vr (define: schema -- google)  Dublin Core is a schema robin fay @georgiawebgurl 2013
  • 12. Very Simple Dublin Core in RDF We can combine schemas robin fay @georgiawebgurl 2013
  • 13. OWL = Web Ontology Language •invented to link ontologies which are classification systems •Attempts to define objects and their relationships •Different “flavors” •“interpreted as a set of "individuals" and a set of "property assertions" which relate these individuals to each other” (wikipedia 2009) •Not a requirement •Sounds familiar to catalogers, right? robin fay @georgiawebgurl 2013
  • 15. Being that this is data driven, we can query, using SPARQL, a standard query language. We’ll talk more about SPARQL later… robin fay @georgiawebgurl 2013
  • 16. •Linked data is: “about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data.” •Think> related, series records, authority files •Libraries already link data. •Projects such as the NYT Linked Open Data project and the Virtual Authority File project are resources of controlled vocabularies. •Verified and digital identity accounts such as openID and claimID to differentiate names robin fay @georgiawebgurl 2013
  • 17. • What is linked data and open data o Linked data is about reusing data o We already do some linked data in our library catalogs and even in our daily lives o The link in a bibliographic record (like an authority record link) is linking data behavior o A link that we share to our friends on facebook is linked data (of sorts) • Linked data is a link to a record/data/content that can then be utilized in some way • Open data is data that available to be used in some way with no barriers to access (licensing, etc.) robin fay @georgiawebgurl 2013
  • 18. Basic principles of linked data It keeps us from having to re-enter or copy information – Making our data: • reusable • easy to correct (correct one record instead of multiples) • efficient • and potentially useful to others It can build relationships in different ways - allowing us to create temporary collections (a user could organize their search results in a way that makes sense to them) or more permanent (collocating ALL works by a particular author more easily; pulling together photographs more easily) robin fay @georgiawebgurl 2013
  • 19. • Advantages (reusable data, potential to provide and built relationships, discoverability) • How library data fits into linked data o FRBR ( a bibliographic FRAMEWORK which is more semantic by nature) RDA ( metadata rules which are not tied to a programming language such as MARC but can work with semantic web standards like XML); IRs, and CMS like Drupal which have semantic web capabilities • RDA expressed as RDFa robin fay @georgiawebgurl 2013
  • 20. The RDF Triple: conceptual Examples same as author of Predicate/verb
  • 21. Tim Berners-Lee’s 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 4. Include links to other URIs, so they can discover more things URIs = Uniform Resource Identifier robin fay @georgiawebgurl 2013
  • 22. What can linked data do for libraries? • URIs creates methods for classifying that can be used (linked to!) by others • Library of Congress has released LCSH as linked data, and OCLC has a modified version of LCSH called FAST as linked data • Linked Data is flexible enough to express entity- relationship relationships such as FRBR/FRAD • Different databases (ILS, ERMS, IRs, local databases, etc.) allowing sharing of data – potentially more consistent data – allowing for collocation across resources and allowing users to easily find resources regardless of source robin fay @georgiawebgurl 2013

  • 26. How cataloging is changing : A changing library and WEB landscape • Automation and new technologies • The web has changed • Large scale bibliographic databases • Cooperative cataloging • Administrative desire to decrease costs • Greater variety of media in library collections (electronic!) • User expectations and needs • FRBR is our data model – semantic web friendly! robin fay @georgiawebgurl 2013
  • 27. • FRBR will give us a way to group things in different ways building relationships between data – by WEMI (Work, Expression, Manifestation, Item) • WEMI is a hierarchy from abstract to the actual thing owned by a library (the well… item!) • Work and Expression can be somewhat conceptual with lots of discussion going on; however, you can loosely think of Work as a concept or idea which is Expressed (think the act of creation; performance) onto/into a physical format (can be digital) aka a Manifestation, of which the library has a copy (Item). robin fay @georgiawebgurl 2013
  • 28. Entity-Relationship Model (new way of storing & organizing data) • Database design model • Entity - a thing with an identity – Entities have attributes (characteristics) • Relationships – Between different entities at different levels • Provides for organization of records in database – “clustering” • Conceptual model of abstract concepts robin fay @georgiawebgurl 2013
  • 29. FRBR and RDA properties element sets
  • 30. “User Tasks” How do catalog users • Find • Identify • Select • Obtain … the resources they want? robin fay @georgiawebgurl 2013
  • 31. Work A distinct intellectual or artistic creation Group 1 Entities (WEMI Hierarchy) Expression Intellectual or artistic realization of a work Manifestation Physical embodiment of an expression of a work Item Single exemplar of a manifestation
  • 33. The FRBR Entity Relationship Model
  • 35. RDA Controlled Vocabularies Closed content type media type carrier type mode of issuance ... and more. Open frequency type of recording language of expression form of musical notation relationship designators (app. I-K) ... and more. robin fay @georgiawebgurl 2013
  • 36. RDA, FRBR, and MARC RDA is our metadata rules to describe our content FRBR is our semantic web friendly data model Currently we use MARC to format our data but we need something better Linked data can be the mechanism – but what about the actual records? robin fay @georgiawebgurl 2013
  • 37. RDA, FRBR, and MARC • Bibliographic records are structured in MARC (a programming language). MARC (MAchine Readable Code) and AACR2 have been working together a long time which means that compromises and workarounds have sometimes be made. This will be true for RDA, too. • MARC is a mixture of controlled access points (series, name authority and subject headings + free text (e.g., contents notes). This provides flexibility and structure but> More free text = less precision in searching = more work for systems to return relevant results robin fay @georgiawebgurl 2013
  • 38. RDA, FRBR, and MARC • Bibliographic records are structured in MARC (a programming language).

This provides flexibility and structure but> More free text = less precision in searching = more work for systems to return relevant results robin fay @georgiawebgurl 2013
  • 39. • MARC existed before AACR2. MARC was developed in the 1960s before most digital technology existed – the web as we know it, ebooks, and Google, did not exist. • Most current catalog systems use MARC, but there are other metadata schemas and programming languages. • Although many systems have not fully utilized all of the fields and functionalities of MARC, it is reaching the end of its lifespan. • The next generation (nexgen) systems can not develop as only MARC based; we need more. RDA, FRBR, and MARC robin fay @georgiawebgurl 2013
  • 40. • Our future systems will probably not use MARC, but some kind of semantic web friendly schema. • Currently, the Library of Congress has started a project called the Bibliographic Framework Transition Initiative • Why? • We need something that is more flexible, not flat in file structure, yet works with a semantic framework. • We need something that works better with different metadata schemas. • This new framework will provide us with enormous functionality in our catalogs and allow us to fully use RDA. It will allow us to move forward into the semantic web world. RDA, FRBR, and MARC robin fay @georgiawebgurl 2013
  • 41. • We have some relationships within our library catalog via the bibliographic data – bib-holding-item (a way to keep all of the parts of a particular thing together) • Bib to authority –series-subject headings (a bib record having linking field(s) to another record(s)) • Authority records – records not visible to the public, but provide the linking points to our bib records and guide the user through variations of the name or title, etc. Linking data in catalogs robin fay @georgiawebgurl 2013

Editor's Notes

  1. For each part a URI.
  2. URIs are kind of like a hook – they allow us to connect things together.
  3. ElaineSvenonius (?) posited that “navigate” (finding works related to a given work by generalization, assn., & aggregation…) should be added, but is not officialFind: resources corresponding to user’s search criteriaIdentify: confirm resource described corresponds to that sought, or distinguish between more than one resource with similar characteristicsSelect: resource appropriate to user’s needsObtain: to acquire or access resource (RDA chap. 4 (7 pp.) on acquisition and access, includes URL)
  4. One of RDA’s characteristics which mean it can work better in linked data environment; many of these are registered on the web online registry of both RDA element sets and values (vocabularies), at http://metadataregistry.org/
  5. One of RDA’s characteristics which mean it can work better in linked data environment; many of these are registered on the web online registry of both RDA element sets and values (vocabularies), at http://metadataregistry.org/
  6. One of RDA’s characteristics which mean it can work better in linked data environment; many of these are registered on the web online registry of both RDA element sets and values (vocabularies), at http://metadataregistry.org/[Show exercises, explain, solicit questions, etc.]
  7. One of RDA’s characteristics which mean it can work better in linked data environment; many of these are registered on the web online registry of both RDA element sets and values (vocabularies), at http://metadataregistry.org/[Show exercises, explain, solicit questions, etc.]
  8. What a FRBRized catalog should give us is better searching tools and enable to see editions more easily; see related titles in different media (e.g., easier to find the work “Dracula” regardless of its physical format – its manifestation). Since FRBR is a data model built on a semantic web framework, it will also enable us to have better, more robust, more semantic web like search tools (like our catalogs). ..while FRBR influenced RDA and FRSAD (Functional Requirements for Subject Authority Data)
