6. Coin-Types as Numismatic Concepts
A coin-type is a general series to which a coin belongs, as defined by typological attributes.
It consists of the following:
Dates of issue
Denomination
Legend
Manufacture type (“struck” for Roman coins)
Material
Mint and/or Region
Persons (authority, magistrate, artist, portraiture, etc.)
Type (iconography)

7. Numismatic Description Standard (NUDS)
LOD-inspired XML schema based on fields described at http://nomisma.org/nuds/numismatic_database_standard
Evolution of Encoded Archival Description for Numismatic Collections presented at CAA in 2009: numismatic ontology
influenced by TEI, EAD, VRA Core, etc. with W3C xlink attributes for semantic linking
See http://wiki.numismatics.org/nuds:nuds
Example: RIC Vol. 1 (Edition 2): Augustus 42a
http://admin.numismatics.org/ocre/display/ric.1(2).aug.42a
object type: Coin (http://nomisma.org/id/coin)
denomination: Denarius (http://nomisma.org/id/denarius)
material: Silver (http://nomisma.org/id/ar)
date: 20-19 B.C. (ISO8601 date -0020 to -0019)
authority: Augustus (http://nomisma.org/id/augustus)
mint: Caesaraugusta (http://nomisma.org/id/caesaraugusta)
region: Spain (http://nomisma.org/id/spain)
associated physical objects (http://numismatics.org/collection/1937.158.423)
also includes obverse types and legends, unlinked

8. Introducing Numishare
Open source web application for creating, managing, and publishing numismatic collections.
See more at: http://code.google.com/p/numishare/
Application Stack
(all open source components)
Cocoon
Solr
eXist
Orbeon XForms

9. Online Coins of the Roman Empire (OCRE)
Metadata extracted either from NUDS
or XTHML+RDFa using standard
nomisma-defined properties

10. Mapping findspots for a coin-type is possible, although not shown in this example

12. Search and Browse: Solr power
Note:
Atom feed
KML results
CSV
visualization
query map
faceted browse

13. Query by URI

14. map generated from Solr search
results processed with XSLT to create
KML, then rendered in OpenLayers

15. RIC Search Goes to 11
Numishare supports fuzzy and wildcard searches through Solr.
P?C? *TAE yields results with PACI AVGVSTAE legends
Useful for more rapid and accurate identifications in the field

16. Managing OCRE in the back-end: Orbeon XForms
Definition: An XForms-based web form gathers and processes XML data using an architecture that separates presentation,
purpose and content.

17. Example of editing a record for a physical coin

19. Also supported: VIAF and Geonames
Most useful for non-Greek and Roman coins for which
nomisma ids have not yet been created
If application language is English – Library of
Congress names are replied and Anglo-American
Cataloging Rules are applied to places

20. Numishare Administration
Other Admin Features:
Create “pages”
Import from CSV
Basic theme and layouts
Control configurations through web
form
Other Coin Form Features:
Upload images through form
Attach images through flickr APIs

21. Use Cases
Research tool for students, scholars, and collectors
Authoritative metadata source for other projects and collections (e.g.,
Portable Antiquities Scheme, OpenContext)
More efficient coin identification at archaeological excavations
Useful for “big data” mining and visualization
JISC Common Repository Interfaces Group (CRIG):
“The coolest thing to do with your data will be thought of by someone else”
