The website is about publications and in particular about the publications of one person, Ullin T. Place. But his publications are related to the publications of others. One could say the website is a digital library of the publications of Ullin T. Place (UTP).

A publication is represented by metadata and one or more files, mainly PDF files.

The metadata of a publication consists of the following fields

• anchor (1) [Note 1]: unique within the website; the anchor is a string of the last author names plus publication date concatenated by hyphens; the string is lowercase and made unique by adding an alphabetic character at the end
• list (1-): possible values are ‘bibliography’, ‘amsterdam’, ‘others’, ‘references’, ‘citing’, ‘talks’ and ‘literature’. The values correspond to lists that can be generated by the website. Bibliography: the publications of UTP. Amsterdam: the Amsterdam lectures (1973-1974). Others: publications about UTP. References: publication to which UTP refers in his publications. Citing: publications that cite UTP. Talks: presentations by UTP. Literature: publications that do not belong to the other lists. Names of more than one list can be entered and separated by a comma; spaces are not allowed.
• author-date (1); author(s) and publication date according to the APA reference style. The last character is always a period.
• title (1): the title according to the APA reference style. The last character is always a period.
• source (0, 1): the source according to the APA reference style. The last character is always a period.
• abstract (0,1)
• note (0, 1)
• keywords (0 – )
• url (0-): URLs of full text outside this website. Preferably a DOI.
• links_to (0-): links from publication to another publication. The links are typed. An outgoing link must always have an incoming link in the linked_by field of another publication (there is a validation script available that checks whether incoming and outgoing links balance). An outgoing link is represented by a string consisting of a code for the type space anchor of the other publication. E.g., ‘ref place-1956’ stands for the present publication referencing the publication with the anchor place-1956; in the linked_by field of the record with anchor place-1956 is a ref link back to the present publication. additional information about the link can be entered between square brackets (comma’s not allowed). Examples of additional information are the pages where a reprinted publication appears in a reprinting publication or the string ‘citations’ for indicating that there are citations in context stored in the database of the website. The links can be repeated by concatenating them by adding commas as separators. The link types are (between brackets the code for the type)
  • reference (ref)
  • citation (cit)
  • reply (reply)
  • review (review)
  • reprint (reprint)
  • related (see)
  • talk (talk)
• linked_by (0-): incoming links from other publications to this publication. See the description of the links_to field.
• download (0 – ): a digital version of the publication is available via this website; a file represented by an URL; downloads are mainly PDF files, but they can also be all kinds of multimedia. This field consists of an URL and a file name.
