christine.oliver@uottawa.ca 1 �Organizing bibliographic information Context for our work in the 21st century: • users interact with bibliographic data in a broad, global context • bibliographic data is managed inside and outside traditional catalogues • no library is an island – everyone’s data is interconnected • metadata supports linking to and aggregating with data from other communities • metadata can be harvested, re-used, and mined 2 �RDA: Resource Description and Access RDA is a package of: ◦ data elements ◦ guidelines and instructions → for creating library and cultural heritage resource metadata → metadata that can be used in traditional catalogues → metadata that is ready for use in linked data applications 3 �2 significant facets of RDA • RDA as a standard for use with current and emerging technologies • RDA as a standard that is being intentionally internationalized 4 �RDA as a standard for use with current and emerging technologies Creator: ipopba -Credit: Getty Images/iStockphoto 5 �A standard for the st 21 century • recording data, not strings machine processing • a shared element set data interoperability • suitable for wide range of technological environments flexibility • optimized for linked data environments ready for the future 6 �RDA is a package of data elements • data elements that can be understood by humans and processed by computers • current reality = vast amounts of bibliographic data • no longer practical to think that the management of bibliographic data will be manually curated • reality of reliance on machine processing • but machines need good data to produce useful results 7 �RDA is a package of data elements RDA = a set of precisely defined data elements (and controlled vocabularies) • each data element contains only one type of data – unambiguous data • RDA has elements for recording data about 13 entities • RDA has over 3,000 elements 8 �RDA data designed for interoperability • clearly defined element set different types of RDA users all share the same element set openly published controlled vocabularies to increase interoperability definition and structure make it easier to map to non-RDA data • recognizable structure for the data elements explicit and widely accepted structure – based on the internationally accepted bibliographic conceptual model: IFLA Library Reference Model (IFLA LRM) 9 �Designed for flexibility Four recording methods • options according to the technological environment in which one operates: • unstructured description • structured description • identifier • IRI – internationalized resource identifier “The methods are listed in order of increasing utility in general applications of RDA data, from low utility to high utility or smart data.” • IRI → for linked data 10 �One standard -- many ways to use it an unstructured description transcribe the name of the author from the title page or automated data capture of information on a title page result = a string of characters a human can decipher and understand a computer cannot process effectively – only good enough for keyword searching 11 �One standard -- many ways to use it IRI – internationalized resource identifier an Internet standard a globally unique identifier, for example, use it to record the name of a person result = a machine-readable string • a human cannot easily decipher and understand • a computer can process very effectively in a linked data application • a computer can retrieve a large amount of information using the IRI and may also link to other information connected to that IRI • expands the potential for exploration 12 �Metadata statement using IRIs subject, object and predicate all recorded using IRIs Screen image from the RDA Toolkit (www.rdatoolkit.org) used

�Ready for the future • optimized for linked data • record RDA data using RDF-based encoding schemes viable alternatives to MARC, such as Bibframe and Share-VDE • many will continue to use MARC formats for a while • RDA is not optimized for MARC, but RDA in MARC still a useful step forward • RDA, especially in the new Toolkit, starts reorienting our thinking in terms of data elements, relationships, using IRIs, etc. 14 �Metadata standard for the • ready for the future • flexible • data that can be used effectively for automated processing • promotes data interoperability st 21 century create metadata that can be used in traditional catalogues and also for the web and linked data environments precise and unambiguous data in welldefined data elements with an articulated structure 15 �RDA as a standard that is being intentionally internationalized Flags globe at shutterstock (vector) ID: 111655109 by Alhovik 16 �An international standard • aligned with international standards sound theoretical framework • accommodating different local traditions responsive to local needs • translations are an integral part of the standard different language versions for use in communities around the globe • in use in countries around the globe governance to reflect international participation 17 �RDA aligned with international standards • RDA is aligned with: IFLA’s International Cataloguing Principles IFLA’s bibliographic conceptual model: IFLA LRM • also includes a statement of relationship to other international standards for example, metadata that can be stored in different encoding schemes, such as MARC 21 and RDF 18 �RDA: implementation of IFLA LRM IFLA LRM = IFLA Library Reference Model the bibliographic conceptual model that consolidates and supersedes the three previous IFLA models: FRBR Functional Requirements for Bibliographic Records FRAD Functional Requirements for Authority Data FRSAD Functional Requirements for Subject Authority Data 19 �Alignment with IFLA LRM • RDA based on an internationally accepted understanding of the structure of bibliographic data • IFLA LRM provides: • the basic structure and organization for the content of RDA • a recognized theoretical framework that was developed through international cooperation and consensus • built-in focus on the needs of the end-user through the user tasks 20 �Not “one size fits all” RDA is designed so that metadata can be created to meet the interests of local communities within a global framework for interoperability. – Gordon Dunsire, Accommodating local cataloguing traditions in a global context, 2018 • basis for data interoperability → the shared element set → data shares the same structure (IFLA LRM) • focus on the common ground we share 21 �Internationalization – a design objective • data harmonization “RDA is designed for an international audience with the expectation that cataloguing agents will make application decisions when desirable” … “Given the flexibility of the guidance and recording methods, the metadata provided by different agents will not necessarily be identical, but as well-formed data it will be understood by any agent when shared. The emphasis is on data harmonization rather than strict compatibility.” RDA > Introduction to RDA > Objectives and principles governing RDA 22 �Accommodation of variations IFLA LRM provides the basic structure for bibliographic data → RDA provides: option to use any of a large number of precise data elements choices on how to record the data options for which instructions to use options for sources of controlled vocabularies (VES) options on how to punctuate and order elements → a cataloguing community makes the choices that suit their needs 23 �Cataloguing community’s choice For example, when using controlled vocabulary (vocabulary encoding scheme) to record data: Structured description Instruction to use one of the RDA vocabulary encoding schemes Followed by instruction to use another suitable vocabulary encoding scheme Examples in RDA also show use of RDA vocabularies and external vocabularies 24 �Instructions for broadcast standard Screen image from the RDA Toolkit (www.rdatoolkit.org) used by permission of the Copyright Holders for RDA (American Library Association, Canadian Federation of Library Associations, and CILIP: Chartered Institute of Library and Information Professionals). 25 �Examples using non-RDA VES at accessibility content Screen image from the RDA Toolkit (www.rdatoolkit.org) used by permission of the Copyright Holders for RDA (American Library Association, Canadian Federation of Library Associations, and CILIP: Chartered Institute of Library and Information Professionals). 26 �Cataloguing community’s decisions • Places within RDA Toolkit for a community to record and share its decisions: policy statements application profiles and other documents (shared or not) community resources 27 �A multilingual standard RDA an international standard 8 – full translations integrated into the original RDA Toolkit 14 – language versions integrated in the RDA Registry (partial translations = names of elements and controlled vocabularies) • a standard that places equal value on all its language versions • English is treated as one of the language versions • English is the version used as starting point for translations, but deliberately called a “version” 28 �A multilingual standard • seamless integration of all language versions in the one RDA Toolkit and RDA Registry • visibility of all the different language communities using RDA • all using the same element set and vocabularies 29 �RDA, a global metadata standard • designed to be easy to use by metadata creators around the globe • a standard to be maintained and developed jointly with representatives from all regions of the globe RDA governance internationalizes decision-making and management Representation from all 6 regions of the globe Africa, Asia, Europe, Latin America and the Caribbean, North America and Oceania 30 �RDA, a framework for interoperability cataloguing communities around the globe operate in different contexts • different technological environments • conventions and practices differ • different needs in linguistic, national, and cultural cataloguing communities our common interest -- providing metadata that fulfills the needs of our end-users -- data that can be processed accurately by computers -- compatibility of bibliographic data across communities 31 �? christine.oliver@uottawa.ca 32 � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Title A name given to the resource Encontro de RDA no Brasil - Edição: 2 - Ano: 2021 (Evento on-line) Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections. For more information see, http://dublincore.org/documents/dces/. Title A name given to the resource RDA, for now and for the future Subject The topic of the resource Catalogação Description An account of the resource The presentation will focus on RDA in the new RDA Toolkit. It is still the same RDA as in the original RDA Toolkit. The standard follows the same objectives and principles, and it continues to support the same ways of working as in the original RDA Toolkit. There are changes, but these changes are not disruptive. The standard looks different, it has expanded in scope, and it has been deliberately internationalized, to accommodate the needs of local cataloguing communities around the globe. It has evolved more fully to achieve its purpose of being an international metadata standard for both current and future environments. The presentation includes an overview of the major developments that occurred during the 3R Project: the impact of the 3R Project itself, the results of aligning RDA with IFLA’s Library Reference Model (IFLA LRM), and the outcomes of internationalization.
