- 1. The Official RDA Toolkit: Opportunities for Enrichment Presented to RDA Day 2023 Birmingham, England, 8th September 2023 Thurstan Young, British Library
- 2. Overview (1) What does RDA say about enrichment?
- 3. Overview (2) Sufficiency The metadata describing an entity should be sufficient to meet the needs of the user with respect to selection of an appropriate entity. Guidance > Introduction to RDA > Objectives and principles governing RDA An RDA description of a resource entity is effective if it conforms to a Minimum description of a resource entity. Add other elements to a minimum description of a resource entity that are deemed useful for identification or access. Guidance > Resource description > Effective description
- 4. Overview (3) Official RDA Toolkit offers means of achieving enriched metadata by supporting: • Identification • Selection • Contextualization
- 5. Overview (4) Official RDA Toolkit offers means of achieving enriched metadata by describing: • Extension Plan • Representative Expressions • Data Provenance
- 6. Extension Plan: Background (1) extension plan A categorization that reflects an intention to extend the content of a work. Resources > Glossary A diachronic work is a work that is planned to be embodied over time, rather than in a single act of publication. When the plan is carried out, the content of the work changes over time by being realized by one or more discrete expressions that are embodied by one or more manifestations. The essence of a diachronic work is a plan for the change of content. An extension plan describes the intended method for extending the content of a work through time. Guidance > Diachronic works
- 7. Extension Plan: Background (2) Extension attributes The RDA/ONIX Framework uses three attributes that provide basic categories for extension plans: Extension requirement Extension mode Extension termination Guidance > Content and carrier > Extension plans
- 8. Extension Plan: Background (3) Extension requirement The extension requirement attribute distinguishes a diachronic work from a static work. A value of not applicable is associated with a static work. A value of essential is associated with a diachronic work if the extension of content is required to sustain the integrity of the work. If the extension plan is not completed, the work loses integrity. A value of inessential is associated with a diachronic work if the extension of content is not required to sustain the integrity of the work. If the extension plan terminates, the previous iterations of the work retain integrity.
- 9. Extension Plan: Background (4) Extension mode The extension mode attribute describes a method that is used to extend the content. A value of integration is associated with a diachronic work that uses replacement to extend the content. A value of succession is associated with a diachronic work that uses accumulation to extend the content.
- 10. Extension Plan: Background (5) Extension termination The extension termination attribute describes the expected duration of the timespan to extend the content. A value of determinate is associated with a diachronic work that has a predetermined end for the extension of content. A value of indeterminate is associated with a diachronic work that does not have a predetermined end for the extension of content.

- 22. Representative Expressions: Background (1) representative expression An expression that is considered a canonical source of data for identifying a work. Resources > Glossary The IFLA library reference model treats as equal all expressions that realize a work. However, certain characteristics of an expression are considered to best represent the intention of the creators of the work. A representative expression that has these characteristics may be assumed to be an original or canonical realization of the work. Manifestations that embody representative expressions may be the specific target of a search using RDA data. There may be two or more expressions that can be treated as a representative expression of a work, and an expression does not need to be extant to be a representative expression. RDA specifies which expression elements are considered significant for the description and distinction of works and provides a corresponding set of work elements. Guidance > Representative expressions

Representative Expressions: Background (2) OPTION Record a value of an element of a representative expression using any of the following elements: Work: aspect ratio of representative expression Work: colour content of representative expression Work: content type of representative expression Work: date of capture of representative expression Work: date of representative expression Work: duration of representative expression Work: extent of representative expression Work: intended audience of representative expression Work: key of representative expression Work: language of representative expression Work: medium of performance of choreographic content of representative expression Work: medium of performance of musical content of representative expression Work: place of capture of representative expression Work: projection of cartographic content of representative expression Work: scale of representative expression Work: script of representative expression Work: sound content of representative expression

Resources > Glossary Data provenance provides information about the metadata that is recorded in an element or set of elements. This information can be used to infer the context and quality of the metadata. Guidance > Data provenance
- 33. Data Provenance: Background (2) The metadata being described by data provenance is treated as a metadata work that consists of a metadata statement or a metadata description set. For example, a descriptive catalogue record is a set of statements about a specific information resource that often includes subsets of statements for the work, expression, manifestation, and item that constitute the resource. The catalogue record is a metadata work that is realized in a specific encoding scheme and embodied by a carrier such as a microfiche or online manifestation… A single metadata statement is a metadata work in itself. It is in turn part of a larger metadata work that consists of multiple metadata statements about one or more entities. Ultimately, every metadata description set is part of a larger metadata work that is the set of all metadata statements about all entities. Guidance > Data provenance

Opportunities for Enrichment: Analysis The Official RDA Toolkit’s options for enriched resource discovery support: • selection policy for and inventory control of diachronic resources based on their anticipated development over time • identification and selection of resources based on their original or canonical characteristics • contextualization and quality assessment of cataloguing metadata at broad and narrow levels

Editor's Notes
- This presentation looks at various opportunities which the new RDA Toolkit offers in terms of achieving cataloguing enrichment. Examples of application are presented both in terms of entity relationship modelling and MARC 21 encoding.
- Let’s look at what the new RDA Toolkit says about extension plans first
- Underpinning the categories of extension plan expressed in RDA are three attributes used in the RDA/ONIX Framework.
- Some of the language used in these attributes reoccurs in RDA’s labels for categories of extension plan.
- And here are those categories expressed as a vocabulary encoding scheme.
- The definitions for each are as follows:
- How does this work in practical terms? Here is an example of a resource entity to be described: a multivolume, textual work entitled “A History of Britain” by the author Simon Schama published in three parts between 2000 and 2002.
- We will choose the successive determinate plan as an as the extension plan which describes our resource entity.
- The concept of extension plan set out by the new RDA Toolkit is not equivalent to the concept mode of issuance set out by the original Toolkit. In the original Toolkit, mode of issuance was an element which conflated the notion of whether a resource consisted of one or more parts with whether or not it was subject to updating. In the new Toolkit mode of issuance is only used to reflect whether a resource is a single unit or, as in this example, a multiple unit.
- Another form of enrichment can be achieved through recording representative expression characteristics using the new RDA Toolkit.
- And here is a list of characteristics which may be used to specify a representative expression.
- Lets return to our resource entity.
- We’re going to record the element content type of representative expression to specify an original or canonical aspect of this work.
- In this case the value assigned for content type of representative expression is “text”
- The element content type of representative expression is, in this case, the same as the content type for the expression which is being described.
- However, it serves to differentiate from other expressions of the same work which do not share the same content type. In this case the content type for the expression being described would be “spoken word” rather than “text”. As an audiobook edition, the expression described could be regarded as a derivative of the written word original.
- The next form of enrichment we’re going to look at is data provenance.
- And here is a list of characteristics which may be used to record data provenance.
- Back to our resource entity
- We’re going to record an aspect of data provenance which relates to a metadata description set, or catalogue record, as a whole. .
- And this is the characteristic we will be recording.
- The element note on metadata work is defined as follows in the new RDA Toolkit:
- In the case of this metadata description set, or catalogue record, the note on metadata work tells as that it started our as a CIP record.
- Now we’re going to do something different. We’re going to record an aspect of data provenance which relates to individual metadata statements, or elements, which form part of a catalogue record.
- And this is the characteristic we will be recording.
- The element source consulted is defined in the new RDA Toolkit as follows:
- In the case of these metadata statements, or elements, describing mode of issuance, extension plan, content, media and carrier type, they all relate to vocabulary encoding schemes of controlled terms. In a MARC 21 context, identifiers for those vocabulary encoding schemes can be appended to controlled terms as a means of recording a source consulted.
- To go one step further, it is possible to record multiple characteristics of data provenance in relation to an individual metadata statement. Let’s take an agent who records metadata and timespan when metadata is published as a couple of examples.
- The element author agent is defined as follows in the new RDA Toolkit:
- And the element related timespan of work is defined as follows:
- In a MARC 21 context it is now possible to link multiple characteristics of data provenance to an individual metadata statement. Here. one coded value dpeaa representing the element author agent is combined with code UK which represents the British Library. Another coded value dpertow representing the element related timespan of work is combined with a timestamp entered in ISO 8601 basic format.
