NUDS:Exchange Format

From Digital Coins Network

NUDS Exchange is an xml schema designed to facilitate the exchange of numismatic information. It derives its element names from the Numismatic Database Standard.

[edit] Format

NUDS-Ex element names are derived from NUDS "field names" and are simply the names rendered as one word in all lower case. For example, "<denomination>Sestertius</denomination>" is a specific instantiation of the "Denomination" field in NUDS.

Each record is enclosed in a "record" element so that a more complete example of NUDS-Ex is:

   <record>
       <language>eng</language>
       <collection>ANS</collection>
       <collectionid>1935.117.226</collectionid>
       <title>Athenian Tetradrachm</title>
       <category>Ancient Greek</category>
       <objecttype>coin</objecttype>
       <denomination>Tetradrachm</denomination>
       <material>AR</material>
       <weight>17.13</weight>
       <manufacture>Struck</manufacture>
       <completeness>complete</completeness>
       <geographic1>Attica</geographic1>
       <mint>Athens</mint>
       <fromdate>-454</fromdate>
       <todate>-449</todate>
       <obversetype>Athena head right.</obversetype>
       <reversetype>Owl stg. r, twig, moon.</reversetype>
       <reverselegend>ΑΘΕ</reverselegend>
       <reference>Starr 196</reference>

   </record>

[edit] Preserving Original Field Names

NUDS-Ex can use attributes to preserve the original field names as used in the source database. This is done by adding a "srcfield" attribute to an element. In the case of the coin above, which comes from the collection of the American Numismatic Society, a qualified NUDS-Ex record would look like:

   <record>
       <language>eng</language>
       <collection>ANS</collection>
       <collectionid srcfield="accnum">1935.117.226</collectionid>
       <title>Athenian Tetradrachm</title>
       <category>Ancient Greek</category>
       <objecttype srcfield="objectype">coin</objecttype>
       <denomination srcfield="denomination">Tetradrachm</denomination>
       <material srcfield="material">AR</material>
       <weight srcfield="weight">17.13</weight>
       <manufacture srcfld="manufacture">Struck</manufacture>
       <completeness>complete</completeness>
       <geographic1 srcfield="region">Attica</geographic1>
       <mint srcfield="mint">Athens</mint>
       <fromdate srcfield="startdate">-454</fromdate>
       <todate srcfield="enddate">-449</todate>
       <obversetype srcfield="obversetype">Athena head right.</obversetype>
       <reversetype srcfield="reversetype">Owl stg. r, twig, moon.</reversetype>
       <reverselegend srcfield="reverselegend">ΑΘΕ</reverselegend>
       <reference srcfield="reference">Starr 196</reference>
       <imageurl>http://www.numismatics.org/lookup.cgi?string=1935.117.226.image</imageurl>
   </record>
