BIBFLOW: what is BIBFLOW?
Was a 2-year project of the UC Davis University Library and Zepheira to investigate the future of library technical services, i.e., cataloging and related workflows, in light of modern technology infrastructure and new data models and formats such as (RDA) and BIBFRAME. It was a research agenda and set of activities to advance our community’s understanding of the resource description landscape – the current and desired future state – and begin to develop a roadmap that the library community can reference for planning investments and changes over the coming years. The roadmap should serve as a bridge from MARC land to linked data land and provide intermediate steps for libraries to eventually move away from MARC entirely. PCC is the key to the success of this transition.

BIBFRAME: What is BIBFRAME?
Wikipedia. (viewed 2017-03-14) defines BIBFRAME, also known as the Bibliographic Framework Initiative, initiated by the Library of Congress, as: "a data model for bibliographic description. BIBFRAME was designed to replace the MARC standards, and to use linked data principles to make bibliographic data more useful both within and outside the library community". After extensive testing and analysis in 2016, BIBFRAME 2.0 is now available with a new vocabulary, with new tools and supporting components to follow. More details can be found in LOC's BIBFRAME 2.0 FAQ.

Linked data : What is linked data?
Linked data is a process designed to automate how resources connect on the web. Developed around several best practices, it's a standard way of using metadata to link pieces of data that represent people, places, ideas, events, and other details in order to automatically generate connections for the user.

Linked data: How does linked data work?
When used in libraries, archives and museums, linked data helps connect pieces of data that were not previously connected. For example, linked data would allow you to trace a person in a photograph on one website, to a postcard on another completely different site, to a diary on yet another site. Based on technologies of the Semantic Web, it also allows to represent specific relationships between people, places and things, indicating, for instance, whether that person in the picture wrote the diary or was mentioned in it, whether the postcard was sent to them, written by them, or mentioned them. Enriching data through linkages allows you to connect information from different sources, resulting in increased visibility of collections and linked knowledge.

Linked data: Why would I want to invest time and resources into linked data? What can it do for me?
Linked Data can facilitate a creation of an open, global pool of shared data that can be used and re-used to describe resources, thus facilitating long-standing cooperation between libraries. ( Library Linked Data Incubator Group Final Report, 2011). Linked data can make it easier to connect
Benefits of the linked data approach: https://www.w3.org/2005/Incubator/lld/wiki/Benefits
" ... Linked Data and especially Linked Open Data is sharable, extensible, and easily re-usable. It supports multilingual functionality for data and user services, such as the labeling of concepts identified by a language-agnostic URIs. ... By using Linked Open Data, libraries will create an open, global pool of shared data that can be used and re-used to describe resources, with a limited amount of redundant effort compared with current cataloging processes."

Linked Data vs Linked open data: What is the difference between linked data and linked open data?
Linked data refers to how data is linked together, i.e. meaningful semantic triples. Linked data can be internal in an organization or it can be available on the web for other organizations to connect to and make use of. If the linked data is available for outside use, it is linked open data.

Linked data: What is the difference between linked data for metadata and for digital objects?
Linked data semantically expresses the connection between two different things. While this is most often metadata, it can also be used for digital objects (a digital photograph, a text document, a website, etc) to relate multiple documents together in meaningful ways. Linked data for digital objects also usually connects metadata to digital objects as well as connecting digital objects together.
Metadata: John Smith → was born in → New York City
Digital Object: document → is final version of → draft document
document → is the transcript of → video recording
chapter → is part of → book
Hybrid metadata and digital object: document → was published on → date
document → is part of → correspondence series

Linked data: How is linked data related to digital repositories?
Linked data can be used to model relationships between metadata and digital objects in digital repositories, for use both within those repositories and by external services or other repositories that use the same names (URIs) for the same things. Models such as the Portland Common Data Model (PCDM) encourage use of linked data to aid this modelling through use of URIs.

Literals: What are literals?
The Free Dictionary by FARLEX defines literals as: "n. Computers A letter or symbol that stands for itself as opposed to a feature, function, or entity associated with it in a programming language"

Problems of the RDF model: Literals: http://milicicvuk.com/blog/2011/07/16/problems-of-the-rdf-model-literals/
"Literals are nodes in an RDF graph, used to identify values such as numbers and dates by means of a lexical representation. Literals may be plain or typed: .... Anything represented by a literal could also be represented by a URI, but it is often more convenient or intuitive to use literals. For example, it’s easier to use the literal “7″ (or “7″^^xsd:integer) than,
for instance, the URI http://dbpedia.org/resource/7_(number). ":
Class: RDF::Literal: includes examples for plain, language tagged, explicitly datatyped, and implicitly datatyped literals: http://www.rubydoc.info/github/ruby-rdf/rdf/RDF/Literal
"In RDF 1.1, all literals are typed, including plain literals and language tagged literals. Internally, plain literals are given the
xsd:string datatype and language tagged literals are given the
rdf:langString datatype. Creating a plain literal, without a datatype or language, will automatically provide the
xsd:string datatype; similar for language tagged literals. Note that most serialization formats will remove this datatype. Code which depends on a literal having the
xsd:string datatype being different from a plain literal (formally, without a datatype) may break. However note that the
#has\_datatype? will continue to return
false for plain or language-tagged literals.
"foo"^^xsd:string,and the rather weird
"foo@"^^rdf:PlainLiteral. The working group is trying to fix this. Now here’s a quiz with some RDF trivia questions. ...."

RDF: What is RDF?
RDF is short for Resource Description Framework, a group of World Wide Web Consortium (W3C) specifications that provide an entity-relationship syntax to help consistently frame, describe, code metadata, and provide access to and link WWW resources.

Semantic web, what is it?
The "semantic web" refers to the process of automating how resources on the web connect to each other, by adding more structured, machine-readable information into our web resources (e.g. webpage encoding and metadata). Linked data is how the semantic web is formed.The semantic web is part of what makes up Web 3.0.

Triples: What is a triple?
A triple is a statement consisting of two things (a “subject” and an “object”) and the relationship between them (“predicate”). It is the basic building block of linked data.
Each element of the triple is identified by a URI.
