2. OpenURL build an OpenURL resolver for music: services artists
releases (i.e., LPs, EPs, singles)
services
all artists and releases will be in electronic music
this will allow more focused music service creation
links to:
amazon.com
google.com
allmusic.com
discogs.com
artistdirect.com
etc.

3. Resources from the class home page additional resources:
matrix defining OpenURL elements
a simplified sub-set
test page
please send me your baseURLs ASAP
resolvers will be chosen using the “cookiepusher”
additional resources:
for the info:allmusic/XXXXX identifiers…

4. OpenURL Arguments Delim Key Equals Value Min Max Description
& url_ver     1 1 OpenURL version.
Fixed value: Z ( Z must be uppercase)
& rft_val_fmt = <fmt-id> 0 1 Identifier of By-Value Metadata Format for a
Referent. Identifier of the Metadata Format used for
the description of the Referent through By-Value
Metadata
& rft_id = <id> 0 * Referent Identifier. Multiple instances of rft_id do
not indicate multiple Referents, but rather multiple
ways to identify a single Referent
& rft.artist = <id> 1 1 Referent Artist. This is the individual, group or
project that is under discussion. Collaborations
should not use multiple instances of this key, but
rather combine the artists into a single rft_artist key.
& rft.genre = <data> 0 * Referent Genre. This refers to the musical style of
the artists. Multiple instances of rft.genre refer to
overlapping musical genres.
& rft.title = <data> 0 1 Referent Title. This is the title of a particular musical
release (e.g., LP, EP, Single).
& rft.date = <date> 0 * Referent Date. This is the release date of a particular
musical release. Multiple instances of rft.date
indicate re-releases.

5. Sample OpenURL (URL-encoded, with linebreaks)
this addr will be different for
each student
?url_ver=Z
&rft_val_fmt=http%3A%2F%2Fwww.cs.odu.edu%2F%7Emln%2Fteaching
%2Fcs695-f03%2F?method%3DgetElement%26element%3Dweek14~mtx%3Amusic.html
&rft.artist=DJ%20Shadow
&rft.title=Endtroducing...
&rft.date=1996
&rft_id=info:allmusic/A7zsyxdyboold
fixed values; you would
parse these if you supported
different OpenURL versions
or referent types
Sample values; check the matrix
for a full list. You must be able
to parse these correctly.
