Recommended format for Author PDF metadata
hi,
i work librarian , i'm responsible thesis department of university library. thesis deposited , archived pdf files. of them accessible online, not.
i advised systematically fill "title" , "author" metadata every pdf deposited in our electronic despository.
my question has "author" metadata. there recommended structure ?
as can think of many different alternatives :
firstname lastname
lastname firstname
lastname, firstname
etc.
as librarian, intuition choose lastname, firstname format (used in dc author/creator element, example), realized whenever saved pdf file , displayed metadata part (via alt d shortcut), show "lastname, firstname" instead of lastname, firstname (for unknown reason adobe pro adds " "). after tests came conclusion coma source of problem. changed mind , adopted lastname firstname format not sure best option.
so if may ask couple of questions, here :
- format recommend author metadata (if any) ?
- why coma generating " " ?
- there specific separator character must use when need fill 2 different names (if given thesis has been written 2 different persons) ? (this question applies "keywords" metadata)
thanks patience , time,
cheers,
jhm
there no rules per se, xmp specification defines dc:creator propername field, meaning should written in way said - "john smith" rather "smith, john". it's down you're doing data - if external searching system wants surname priority, it.
the fields in pdf properties dialog 'description' tab document information block in pdf standard, independent of xmp metadata. although these di fields ones people at, in formal catalog system xmp object takes priority (indeed, in iso pdf/a standard supposed ignore di fields completely).
document information fields stored in pdf file strings rather xml entities. commas confuse parser thinking seeing array, trigger acrobat wrap entries in quotes. assume comma , single space part of individual term, if want create list use semicolons or multiple spaces between words. senicolons win on spaces:
- doe, john;lord lucan ;barney,dinosaur,the purple stored "doe, john"; lord lucan; "barney,dinosaur,the purple"
- this,is,not,one, person stored "this,is,not,one"; person because double-space term separator.
the important thing remember xmp dc:creator entry updated whenever change di author field, not follow same rules. xmp propernames ok spaces don't commas or semicolons - first example above appear in xmp tree as
- doe
- john
- lord lucan
- barney
- dinosaur
- the
- purple
this reinforces idea of using names as-spoken. lord lucan has survived trip xmp, john doe has become 2 people. barney beyond hope; in many, many ways .
