ID values: general notes [173]


General information on use of id= in WWP texts, including guidelines for choosing values


ID values are used to uniquely identify a particular element, so thatit can be pointed at by other elements (to create links and references of various sorts). In order for a given file to parse, its id values must be unique within the file. However, when our individual files are brought together to form a completed textbase, the id values will need to be unique not only within the file but within the textbase as a whole.

For current encoding purposes, encoders need only create id values which are unique within the file they are currently encoding. They may invent any system of ids which they find convenient (and lucid to other encoders and WWP staff).

Later on, as part of the completion of the textbase, a routine will be written which will go through the entire textbase and replace all existing id values with new ones which are unique across the textbase.

Notes and anchors

Values for id= on <note> elements and on the elements to which notes point (including <anchor> and any other element used for this purpose) should be of the following form:

--for notes, value should be n001, n002, etc., with sufficient leading zeroes to accommodate the total number of notes in the document

--for anchors, value should be a001, a002, etc., matching the numeration of the corresponding <note> elements

Divisions and pages

Values for id= on elements which are pointed to by indexes and tables of contents should use prefix letters matching the element itself (e.g. “div001”, “p001”) to make it easy to see what kind of element is being pointed to.

Cast lists

For the id values in cast lists, the WWP has developed a system to ensure consistency between files, since many of our plays are taken from larger collections. We recommend that id values for each character include a short prefix indicating the name of the play, followed by three letters of the character’s name, as in the following (fictitious) examples:

WOOblo (Lady Blown-Over, from “The Public Wooing”)

WITfee (Mr. Feeble, from “The Female Wits”)
