<p>Pitman: /* What sort of characters do you use? */</p> <hr /> <div>==What sort of characters do you use?==<br /> UTF-8<br /> <br /> ==Each page in AcaWiki has a unique identifier which is a UTF-8 string derived in some automated way from user input. Following are some questions about that process and the use of such identifiers==<br /> <br /> ==How exactly is the identifier derived from user input?==<br /> <br /> ==What if any system is in place to avoid different AcaWiki summaries for the same article? Or is this allowed/encourged?==<br /> <br /> ==What is any system is in place to handle two different articles with the same title?==<br /> <br /> ==How is it decided if two articles are the same, or should be considered the same? (this is an issue of FRBR: different versions/manifestations/... of the same work)==<br /> <br /> ==Same question for Books==<br /> <br /> ==The current metadata schema is inappropriate for books, or in fact anything other than articles. Are there plans to improve this? Why not allow summaries of lectures, experiments, datasets, videos? Obviously some metadata challenges there, but if the metadata standard is kept simple enough there seems to be no conceptual obstacle to writing a summary of any document or resource whatever==<br /> <br /> ==What if any commitment does AcaWiki provide to stability of article idntifiers?==<br /> <br /> ==What if any system is in place to allow bulk upload of metadata, e.g. from BibTeX or similarly structured file, to create multiple AcaWiki entries?==<br /> <br /> ==Does AcaWiki support the creation of &quot;stubs&quot; (in Wikipedia terminology) which would be placeholders with just enough metadata to identify an article (e.g. a BibTeX record)? I think it should, as this lowers the bar to participation of other users who could start summarizing an article without having to upload its metadata==</div>
