What metadata formats will be accepted?

VI. What metadata formats will be accepted?
• Publishers have the option of submitting metadata in one of three formats below. The “preferred” format for submitting metadata is MODS. This format requires the least amount of preprocessing by NAL staff and records in this format should appear more quickly in AGRICOLA than those in the JATS or PubMedDTD formats. Templates to be used to create records and examples of each format are attached below.

How are entity references coded (Symbols that need to be converted to codes)?

Some characters have a special meaning in XML.
If a “less than”( "<" ) character is placed inside an XML element, it will generate an error because the metadata parser interprets it as the start of a new element.
It will generate an XML error: <message>if salary < 1000 then</message>
To avoid this error, replace the "<" character with an entity reference: <message>if salary &lt; 1000 then </message>
There are 5 predefined symbols that need to be converted to codes:

What is XML?

Extensible Markup Language (XML) defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.
Tag: A markup construct begins with “< “and ends with “/>"

start-tags: <section>
end-tags: </section>

What are PubAg's metadata requirements?

Each article to be indexed must have corresponding metadata.

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

The schema declaration must be in the root element of the metadata.

Only the tags listed in the schema or DTD should be used.

HTML tagging should not be used.

What is the process for submitting metadata?

A. Publisher emails Chief Collection Development Librarian of its desire to have a journal indexed in ARICOLA and its willingness to contribute metadata. Contact:
B. Journal is evaluated to determine if it will be accepted for indexing in AGRICOLA. Evaluation criteria include scope of the journal’s content and overall quality of the journal.

What is metadata?

Metadata is usually defined as “data about data”.

In terms of AGRICOLA, metadata is structured data that contains basic citation information about each article (e.g. , article title, abstract, journal title). The structured nature of metadata allows it to be ingested, processed and displayed in a standard manner.

What content is not Indexed in AGRICOLA?

The following types of content are not indexed in AGRICOLA:
Abstract (no associated article)
Article in which the author’s name is a pseudonym
Basic biographical information/obituaries
