What are AGRICOLA’s metadata requirements?

All metadata must be “well-formed” and “validated” against an XML schema or DTD (Document Type Definition).

Well formed XML has all metadata tags opened and closed in the proper order and has a declaration (DTD or XML schema) at the top of the file of records, with the proper attributes.

The purpose of a DTD (Document Type Declaration) or XML Schema is to define the building blocks of an XML document with a list of elements and attributes.

How do I send metadata to NAL?

Metadata files are sent to NAL using a File Transfer Protocol (FTP).

FTP is a standard Internet protocol for transmitting files between computers on the Internet. Like the Hypertext Transfer Protocol (HTTP), which transfers displayable Web pages and related files, and the Simple Mail Transfer Protocol (SMTP), which transfers e-mail, FTP is an application protocol that uses the Internet's TCP/IP protocols. FTP is commonly used to transfer files from your computer to other servers.

What data elements are required on each record?

The following metadata elements are required on all records that are indexed. Each element has examples below.

  • Declaration (XML Schema or DTD---is required above the first record)

  • Article title (in English)

  • Personal author(s)/contributor(s); affiliation of the first author

  • Language (if no language is noted, English is assumed)

  • Abstract (in English)

  • Pagination (first page, last page, if noted)

  • Journal title

What are the XML Schema or DTD declarations for each format?

A schema or DTD (Document Type Definition) describes the structure of an XML record as well as the
relationship of the elements to the application. It must appear at the
beginning of the first record of a file of records, or at the beginning of each record if a file contains only
one record. Records without a schema or DTD will be rejected.

Below are the schema and DTDs for the three metadata formats that can be employed on AGRICOLA metadata records.  

What metadata formats will be accepted?

Publishers have the option of submitting metadata in one of the three formats noted below. The “preferred” format is MODS, unless the publisher has already created records in JATS or NLM DTD.  MODS records require the least amount of preprocessing by NAL staff and will be available in AGRICOLA more rapidly than those in either or JATS or the NLM DTD.   Templates and sample records are provided in attachments below.
