A ContextObject for Books is a metadata package that describes a reference to a book.
Here's the smallest amount of information that you need to know to make correct, minimized, NISO OpenURL 1.0 ContextObject for books:
a 1.0 OpenURL ContextObject using the "book" metadata format can be made as follows
If you append a ContextObject to the end of
<baseurl>?url_ver=Z39.88-2004&, you get a valid 1.0 OpenURL link.
<baseurl> is the address of an OpenURL link service.
ctx_ver=Z39.88-2004 says "this is a version 1.0 OpenURL ContextObject".
rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Abook says "this URL uses the info:ofi/fmt:kev:mtx:book metadata format to describe the thing that the link is about". (Note the percent encoding!)
The journal metadata
<key>s are summarized below (order does not matter, all elements are optional.) Values need to be URL-encoded. In other words:
<space> --> %20 # --> %23 % --> %25 & --> %26 + --> %2B / --> %2F < --> %3C = --> %3D > --> %3E ? --> %3F : --> %3AYou also need to escape accented characters, such as:
é --> %C3%A9 ü --> %C3%BCbut you'll want professional help for them!
If you're reading a ContextObject, note that some implementations may URL encode ALL the characters in the values, not just the ones listed here!
It's strongly recommended that you add a "referrer id" to say who made the ContextObject. Do it like this:
If you have a doi or a url for the thing you're describing, you can add them like this:
|rft.btitle||The title of the book. This can also be expressed as title, for compatibility with version 0.1. "moby dick or the white whale"|
|rft.isbn||International Standard Book Number (ISBN). The ISBN is usually presented as 9 digits plus a final check digit (which may be "X"), i.e. "057117678X" but it may contain hyphens, i.e. "1-878067-73-7"|
|rft.aulast||First author's family name. This may be more than one word. In many citations, the author's family name is recorded first and is followed by a comma, i.e. Smith, Fred James is recorded as "aulast=smith"|
|rft.aufirst||First author's given name or names or initials. This data element may contain multiple words and punctuation, i.e. "Fred F", "Fred James"|
|rft.auinit||First author's first and middle initials.|
|rft.auinit1||First author's first initial.|
|rft.auinitm||First author's middle initial.|
|rft.ausuffix||First author's name suffix. Qualifiers on an author's name such as "Jr.", "III" are entered here. i.e. Smith, Fred Jr. is recorded as "ausuffux=jr"|
|rft.au||This data element contains the full name of a single author, i. e. "Smith, Fred M", "Harry S. Truman". (au is repeatable)|
|rft.aucorp||Organization or corporation that is the author or creator of the book, i.e. "Mellon Foundation"|
|rft.atitle||Chapter title. Chapter title is included if it is a distinct title, i.e. "The Push Westward."|
|rft.title||Book title. Provided for compatibility with version 0.1. Prefer btitle.|
|rft.place||Place of publication. "New York"|
|rft.pub||Publisher name. "Harper and Row"|
|rft.date||Date of publication. Book dates are assumed to be a single year.|
|rft.edition||Statement of the edition of the book. This will usually be a phrase, with or without numbers, but may be a single number. I.e. "First edition", "4th ed."|
|rft.tpages||Total pages. Total pages is the largest recorded number of pages, if this can be determined. I.e., "ix, 392 p." would be recorded as "392" in tpages. This data element is usually available only for monographs (books and printed reports). In some cases, tpages may not be numeric, i.e. "F36"|
|rft.series||The title of a series in which the book or document was issued. There may also be an ISSN associated with the series.|
|rft.spage||First page number of a start/end (spage-epage) pair. Note that pages are not always numeric.|
|rft.epage||Second (ending) page number of a start/end (spage-epage) pair.|
|rft.pages||Start and end pages for parts of a book, i.e. "124-147". This can also be used for an unstructured pagination statement when data relating to pagination cannot be interpreted as a start-end pair, i.e. "A7, C4-9", "1-3,6". This data element includes the OpenURL 0.1 definition of "pages".|
|rft.issn||International Standard Serials Number (ISSN). The issn may contain a hyphen, i.e. "1041-5653". An ISSN in the book format is often associated with a series title.|
|bici||Book Item and Component Identifier (BICI). BICI is a draft NISO standard.|
