This page describes the RIS response format in detail.
The RIS (Research Information Systems) format is selected by ending a URL path with the suffix .ris. This format was defined originally by Research Information Systems, Inc., and has since become one of the most widely used formats for handling bibliographic references.
This format is not very flexible. There is no way to include comments, file attributes, or any information other than reference entries. As a result, if you generate this file with the parameters showsource and/or count, it will contain one or more dummy entries at the top that convey this requested information.
The first few lines of the file are defined by the file format, and provide some general information:
The Paleobiology Database
If you have specified the parameter showsource, then the following two dummy entries will appear at the beginning of the file. See the file format for details of how these entries are encoded.
The exact URL that was used to generate the contents of this file
The date and time at which this file was generated
The parameter value(s) that were used to generate the contents of this file. One of these lines will be present for each separate parameter.
The following entry will also be included if you specify showsource. A second entry is necessary because the RIS specification allows only one UR tag per entry.
The documentation page for the URL path that was used to generate the contents of this file. This page will describe the parameters accepted, and how they are used to determine the result set. It will also describe the fields that make up the result.
If you specify the parameter count, the following dummy entry is also added at the beginning of the file. It specifies the number of records in the result set, along with the number actually returned. This may be smaller depending on the value of the limit and offset parameters.
Records Found = the total number of records in the result set
Records Returned = the number of records actually returned
Following these dummy header entries, the remainder of the entries in the file make up the result set. Each of these entries will contain lines with some or all of the following tags, depending upon what information is stored in the database about each reference.
The publication type, i.e. JOUR for a journal or BOOK for a book
A unique identifier for this reference
The title of the work
The secondary title, i.e. the title of the journal or monograph series in which the work appears
The author(s) of the work. One of these lines will be present for each listed author
The editor(s) of the work. One of these lines will be present for each listed editor
The year of publication
The volume number, if any
The issue number, if any
The first page
The last page
The languge of the work
