4. 4 What am I describing? [tasks are referred to as: cataloging, describing, registering, managing, creating metadata …] Need to understand: 1. Catalog level 2. Work vs. image 3. Related works

5. 5 1. Catalog Level ItemGroupVolumeCollectionSeriesSetComponent

6. 6 Works may be –complex, consisting of multiple parts, –created in series First question: Are you dealing with a part of a work that belongs to a larger whole?

7. 7. Catalog Level 1. Item – an individual object or work, may be composed of multiple parts or components

8. 8. Catalog Level 2. Group An archival group (or record group) is an aggregate of items that share a common provenance. –several thousand items (e.g., the entire body of drawings, models, and written documents from an architect's office) – a few items (e.g., a handful of surviving drawings from one architectural project).

9. 9 2. Group (cont.) a group often contains many different types of objects cataloging focuses on the description of coherent, collective bodies of works

10. 10 3. Volume A volume comprises sheets of paper, vellum, papyrus, or another material that are bound together. –printed books, manuscripts, sketchbooks, or albums. Catalog Level

11. 11 4. Collection A collection comprises multiple items that are conceptually or physically arranged together for the purpose of cataloging or retrieval. –A collection differs from an archival group because the items in a collection are bound informally for convenience and do not necessarily share a common provenance or otherwise meet the criteria for an archival group.. Catalog Level

12. 12 5. Series A series comprises a number of works that were created in temporal succession by the same artist or studio and intended by the creator(s) to be seen together or in succession as a cycle of works.. Catalog Level Image source: http://www.kellypacker.com/portfolio/art_work_by_seri es/category/self-portraits/

13. 13 6. Set A set is an assembly of items that the creator intended to be together (e.g., a tea set, a desk set, a pair of terrestrial and celestial globes). –A set differs from a collection in that it is typically smaller and was intended by the creator to be grouped together.. Catalog Level the object comprises bowl, lid, and stand

14. 14 7. Component A component is a part of a larger item. –A component differs from an item in that the item can stand alone as an independent work but the component typically cannot or does not stand alone (e.g., a panel of a polyptych, an architectural component).. Catalog Level

15. 15 Levels of cataloging in different disciplines Most common levels: –groups, subgroups, volumes, and single items Archives: –group level – intellectual or physical groups Museums: –item level -- assigning accession numbers and other catalog information to every individual object in their collections. Libraries: –volume level -- typically do not catalog individual prints or illustrations in the pages of a volume.

16. 16 A work –is a distinct intellectual or artistic creation limited primarily to objects and structures made by humans –including built works visual art works cultural artifacts … A work is a physical entity that exists, has existed at some time in the past, or that could exist in the future. 2. Work vs. Image

17. 17 2. Work vs. Image An image –is a visual representation of a work. –It typically exists in Photomechanical format Photographic format digital format –In a typical visual resources collection, an image is a slide, photograph, or digital file. –Images do not include three-dimensional physical models, drawings, paintings, or sculptures, which are works in their own right.

18. 18 Data set describing a chair that was documented by a photograph. The photograph was later copied to a slide format and scanned to create a digital image. Frederick C.

24. 24 Relationships between Work and Image Records In a relational database structure –a record for the image would be linked to a record for the work

25. 25 one work – many images – a work may be linked to multiple images (e.g., when there is more than one image of the work) Stonehenge

26. 26 –an image may be linked to multiple works (e.g., when more than one work appears in the same image) one image – depicts multiple works

27. 27 3. Related works Related Works are those having an important conceptual relationship with each other Records for Related Works are linked to each other in the database. An intrinsic relationship is essential and must be recorded to enable effective searches. An extrinsic relationship is not essential; although recording it may be informative, the cataloger need not identify the extrinsic relationship during the cataloging process.

28. 28 Intrinsic relationship Intrinsic relationship -- a direct relationship between two works Whole-Part Relationships Group and Collection Relationships Series Relationships Components and Architectural Works

29. 29 Extrinsic Relationships Extrinsic Relationships -- two or more works have a relationship that is informative, but not essential The described work and the referenced work can stand independently. = a see also reference in a bibliographic record temporal association: e.g., with works done after the original work, such as works that clearly reference other works while not necessarily being copies of them. spatial association: e.g., two or more works intended to be seen together.
