The most important parameters are these: result Specifies which result element to use for each MARC record in the input: TEI means to produce a complete tadpole TEI document, containing a header with a rudimentary text structure. teiHeader means to produce just the header, without the TEI wrapper element and rudimentary text. If the input contains more than one MARC record, the set of resulting elements (whether TEI elements or teiHeader elements) will be wrapped in a teiCorpus element regardless of the value of result. marcitem Specifies whether the MARC record in the input describe the source of the TEI document, or the TEI document itself. input: source means the MARC record describes the source, not the TEI document itself. tei-from-source means the MARC record describes the TEI document itself, and was prepared with the source of the TEI document in hand. tei-from-digital means the MARC record describes the TEI document itself, and was prepared without the source of the TEI document in hand, only the digital object (page scans, etc.) itself. The marcitem determines whether certain information in the MARC record (for example, the edition statement) is copied into the TEI header as a child of fileDesc or as a descendant of sourceDesc.

Additional parameters include: idno Use the value specified both as the value of the id attribute on the TEI element (if one is generated) and as the value of an idno element in the publication statement. usertext Supplies the name of a file containing various bits of user-supplied text to be inserted at appropriate places in the output. (For example, when the MARC record describes the source, not the TEI document, the publication statement for the TEI document will typically identify the project which is creatign the TEI document; appropriate XML should be provided in the document named in the usertext parameter.) Defaults to user-supplied-text.xml, which (as shipped) contains data used by Indiana University.. beautification Specifies whether trailing punctuation should be stripped from certain values before the values are copied to the output. 1 means yes, attempt to strip the non-significant punctuation. 0 means no, do not attempt to strip non-significant punctuation, just copy things as they are. Because MARC records vary so much in their punctuation practice, and because sometimes the trailing punctuation really does belong to the value (e.g. a title ending in the word etc.), Value beautification is at best an approximation: sometimes it strips characters that shouldn't be stripped, and sometimes it leaves characters that should be stripped. Turning it off, on the other hand, will leave a large number of extraneous commas, slashes, and full stops in personal names and work titles. Either way, ideally the header should be cleaned up by hand. sourceDesc Specifies how the source description will be tagged. Known values are: biblFull Later, biblStruct and possibly other values will also be supported.
