My feedback concerns that draft bibframe representation for theses, which is at http://bibframe.org/vocab/Dissertation.html Currently the gloss for this is "A subclass of Language Material Works used to describe students' works such as theses, dissertations, etc." My four points of feedback are: (a) Some theses (for example Canterbury's D.Sc. by thesis) are submitted by authors who are not students in any conventional sense. (The regulations at http://www.canterbury.ac.nz/regulations/award/dsc_regs.shtml make it clear that no new enrolment, fix period of study or classes are required) (b) Some theses (for example New Zealand School of Music's Master of Music in Composition) are not Language Material Works but Notated Music Works. (c) Some theses (for example most theses by publication) are relatively complex compilations of works. (d) All of the Dissertation properties are institutionally-oriented, but the gloss talks about a student and not an institution. (e) It's unclear (to me) whether failed and unsubmitted dissertations are Dissertations or Manuscripts (or both). I suggest moving Dissertation to be a subclass of Works. My suggested gloss is: "A subclass of Works intended to be submitted to a qualification-granting institution, such as theses, dissertations, compilations, etc." cheers stuart -- Stuart Yeates Library Technology Services http://www.victoria.ac.nz/library/
