[[Category:Text]]

Text-based documents should contain a CC marker — a graphic or line of text stating the license — wherever a copyright notice would go, such as in a footer or on a cover page. For documents containing images, markers should ideally include the CC icons and full URL to the license. For plain text documents, the CC icons may be replaced with the name of the license (e.g. Creative Commons Attribution- Noncommercial) or the abbreviation (e.g. CC BY-NC). In both cases the full URL to the license should be included. A copyright notice stating the author(s), date, and copyright should also be included.

== Create ==
# For '''documents which support images''', marks should ideally include the CC icons in addition to the full URI to the license. See [[Marking Image]] to learn how to make your own mark.
# For '''plain text documents''', the CC icons may be replaced with the name of the license or the abbreviation (eg. CC-BY-SA)
# '''Deed''': For longer works, consider including the common deed or legal deed.

[http://www.adobe.com/products/xmp XMP] ([http://en.wikipedia.org/wiki/Extensible_Metadata_Platform Extensible Metadata Platform]) facilitates embedding metadata in files using a subset of RDF. Most notably XMP supports embedding metadata in PDF and many image formats, though it is designed to support nearly any file type.

Creative Commons is recommending XMP as the preferred format for embedded metadata, given its [http://web.archive.org/web/20070426051136/http://labs.adobe.com/technologies/xmptoolkit/#FAQ support for numerous file formats] and the balkanized state of embedded metadata standards. Others are coming to a similar conclusion; Microsoft has announced support for [http://blogs.msdn.com/pix/archive/2006/08/23/715340.aspx XMP in Vista applications] and Jon Udell [http://blog.jonudell.net/2007/02/14/truth-files-microformats-and-xmp/ notes] "There’s also good support in .NET Framework 3.0 for reading and writing XMP metadata." Note that even when embedded with XMP metadata, Creative Commons recommends a licensed document include a visible copyright notice; [[Marking|format-specific recommendations]] for visible notices are available.

The Creative Commons [http://www.creativecommons.org/license/ licensing process] offers a XMP template which may be used to mark files within XMP-supporting [[XMP help for Adobe applications|Adobe applications (step-by-step how-to document)]]. An [http://wiki.creativecommons.org/Adobe_Metadata_Panel XMP FileInfo panel] is also available.

== Specifying License Information ==

XMP [http://www.adobe.com/devnet/xmp/ defines] a rights management schema (see XMP Specification, p. 42). Creative Commons sets the following properties (example values):

* '''xmpRights:Marked''' — ''False'' if Public Domain, ''True'' otherwise.
* '''xmpRights:WebStatement''' — ''http://example.com/pdf-metadata.html'' (Replace with URL containing metadata about the XMP-embedded file; this is referred to as the [[WebStatement|Web Statement]].)
* '''xmpRights:UsageTerms''' — An optional field describing legal terms of use; Creative Commons recommends that when present this take the form ''This work is licensed to the public under the Creative Commons Attribution-ShareAlike license http://creativecommons.org/licenses/bysa/2.0/ verify at http://example.com/pdfmetadata.html'' (Replace URL following 'verify at' with URL containing metadata about the XMP-embedded file; this is typically the URL specified by '''xmpRights:WebStatement'''.)
''This work is licensed to the public under the Creative Commons Attribution-ShareAlike license http://creativecommons.org/licenses/by-sa/2.0/ verify at http://example.com/pdf-metadata.html'' (Replace URL following 'verify at' with URL containing metadata about the XMP-embedded file; this is typically the same URL specified by '''xmpRights:WebStatement'''.)

We also define a Creative Commons schema ''http://creativecommons.org/ns#'' whose common prefix is cc. It currently has the following properties:

* '''license''' — The license URL; for example, ''http://creativecommons.org/licenses/by-sa/2.0/''.
* '''morePermissions''' — A URL where additional permissions (commercial licensing, etc) are available.
* '''attributionURL''' — The URL to use when attributing this work.
* '''attributionName''' — The creator's preferred name to use when attributing this work.

== Verification Links and XMP ==

A publisher can add boost confidence in embedded metadata by providing a '''verifying web statement'''. A verifying web statement is a URL which contains metadata with assertions matching those embedded in the file. The difference is that instead of making the assertions about a URL, the assertions are made in reference to the SHA-1 hash of the file.

For example, the example web statement <code>http://example.com/pdf-metadata.html</code> would include metadata encoded as [[RDFa]].

<code><pre>
<p>The document example.pdf is licensed under a
<a about="urn:sha1:MSMBC5VEUDLTC26UT5W7GZBAKZHCY2MD" rel="license"
href="http://creativecommons.org/license/by/3.0/">
Creative Commons Attribution 3.0</a> license.
</a>
</p>
</pre></code>

When processing a file containing an embedded web statement, an application can retrieve the statement and parse it for additional metadata. If matching assertions are found which apply to the calculated SHA-1 hash of the file, the application can display an indicator noting increased confidence in the metadata. This approach has the added benefit of taking advantage of an existing mechanism (copyright take-down procedures) in order to break the confidence in the case of inappropriately licensed material.

License Deeds (Metadata)

2011-02-17T23:30:15Z

John Doig: /* Work Registration */

Creative Commons license deeds will display information about the referring work if available. This page documents what information is displayed by the deeds.

== How it Works ==

When you visit a CC legal deed by clicking on a link from a licensed work, CC looks at the page you came from (the referrer) to see if it contains information about the licensed work. This information can include how the creator wants to be attributed, who identified a work as in the public domain, etc. If present, this information is displayed for the user, and used to generate copy and paste attribution/citation HTML.

=== Limitations ===

Works that require a password to access them can not be checked by the server software.

If the referring page contains multiple works under the same license (even with properly scoped metadata), we can not determine which link was clicked on. In that situation, we err on the side of certainty and do not display the information.

If the software can not unambiguously determine the title or attribution information, we err on the side of certainty and do not display the information.

== Features ==

The Creative Commons License Deeds will provide extra information about the referrer in three general categories:
* How to attribute/cite the work
* Work registration details
* Where to read more permissions assigned to the work

=== Work Attribution / Citation ===

The standard Creative Commons License Class Deeds(all non-Public Domain licenses) will display a notice instructing how the referrer must be attributed and generate an HTML+RDFa marking that can be used to attribute the work when sufficient metadata is available on the referring page. The Public Domain Deed's provide similar functionality; an HTML+RDFa string that can be used as a citation for the referring work in the Public Domain when sufficient metadata is available. The tables below describe which metadata triples must be available, and how each triple can affect the output seen on the deeds.

{{Infobox|This document contains prefixed identifiers for RDFa predicates, a table of these prefixes is presented at the bottom of this document. }}

=== Work Registration ===

In order for the license deeds to display information about a work's registration, there must exist a triple for '''sioc:has_owner'' on the referring document.

When a valid CC Network user profile URI is specified as the '''sioc:has_owner''', the resulting RDFa graph will look like the following:

<pre>
<http://example.com/> <sioc:has_owner> <https://creativecommons.net/johndoig/>
<https://creativecommons.net/username/> <sioc:name> "Username"
<https://creativecommons.net/username/> <sioc:member_of> <https://creativecommons.net/>
<https://creativecommons.net/> <dct:title> "CC Network"
<https://creativecommons.net/> <sioc_service:has_service> <https://creativecommons.net/r/lookup/>
<https://creativecommons.net/r/lookup/> <sioc_service_protocol> <http://wiki.creativecommons.org/work-lookup>
</pre>

In order for this graph to form, the URI '''https://creativecommons.net/username/''' must be a valid CC Network profile URI, and the user needs to have registered the work ('''http://example.com/''') with their account on the CC Network. When those two conditions are met, the license deeds will display a notice that reads:

<div style="background:#D4EFB9;padding:1em !important;font-size:1em !important;line-height:1em !important;">
[https://creativecommons.net/username/ Username] has registered [https://creativecommons.net/r/lookup?uri=http://lessig.org/blog/ this work] at the [https://creativecommons.net/ CC Network]
</div>

=== More Permissions ===

When the referring document contains [CCPlus] metadta, the License Deed will display information to the user where they may discover more information regarding the permissions to the work. In order for the License Deed to display the information, the triple for the predicate '''cc:morePermissions''' mapped to a URI of a document detailing the extra permissions/restrictions associated with the referring work.

== Examples ==

=== Work Registration ===

In order for the license deeds to display information about a work's registration, there must exist a triple for '''sioc:has_owner'' on the referring document.

When a valid CC Network user profile URI is specified as the '''sioc:has_owner''', the resulting RDFa graph will look like the following:

<pre>
<http://example.com/> <sioc:has_owner> <https://creativecommons.net/johndoig/>
<https://creativecommons.net/username/> <sioc:name> "Username"
<https://creativecommons.net/username/> <sioc:member_of> <https://creativecommons.net/>
<https://creativecommons.net/> <dct:title> "CC Network"
<https://creativecommons.net/> <sioc_service:has_service> <https://creativecommons.net/r/lookup/>
<https://creativecommons.net/r/lookup/> <sioc_service_protocol> <http://wiki.creativecommons.org/work-lookup>
</pre>

In order for this graph to form, the URI '''https://creativecommons.net/username/''' must be a valid CC Network profile URI, and the user needs to have registered the work ('''http://example.com/''') with their account on the CC Network. When those two conditions are met, the license deeds will display a notice that reads:

<div style="background:#D4EFB9;padding:1em !important;font-size:1em !important;line-height:1em !important;">
[https://creativecommons.net/username/ Username] has registered [https://creativecommons.net/r/lookup?uri=http://lessig.org/blog/ this work] at the [https://creativecommons.net/ CC Network]
</div>

License Deeds (Metadata)

2011-02-16T19:24:38Z

John Doig: /* Work Registration */

Creative Commons license deeds will display information about the referring work if available. This page documents what information is displayed by the deeds.

== How it Works ==

When you visit a CC legal deed by clicking on a link from a licensed work, CC looks at the page you came from (the referrer) to see if it contains information about the licensed work. This information can include how the creator wants to be attributed, who identified a work as in the public domain, etc. If present, this information is displayed for the user, and used to generate copy and paste attribution/citation HTML.

=== Limitations ===

Works that require a password to access them can not be checked by the server software.

If the referring page contains multiple works under the same license (even with properly scoped metadata), we can not determine which link was clicked on. In that situation, we err on the side of certainty and do not display the information.

If the software can not unambiguously determine the title or attribution information, we err on the side of certainty and do not display the information.

== Features ==

The Creative Commons License Deeds will provide extra information about the referrer in three general categories:
* How to attribute/cite the work
* Work registration details
* Where to read more permissions assigned to the work

=== Work Attribution / Citation ===

The standard Creative Commons License Class Deeds(all non-Public Domain licenses) will display a notice instructing how the referrer must be attributed and generate an HTML+RDFa marking that can be used to attribute the work when sufficient metadata is available on the referring page. The Public Domain Deed's provide similar functionality; an HTML+RDFa string that can be used as a citation for the referring work in the Public Domain when sufficient metadata is available. The tables below describe which metadata triples must be available, and how each triple can affect the output seen on the deeds.

{{Infobox|This document contains prefixed identifiers for RDFa predicates, a table of these prefixes is presented at the bottom of this document. }}

==== Standard Licenses ====

=== Work Registration ===

In order for the license deeds to display information about a work's registration, there must exist a triple for '''sioc:has_owner'' on the referring document.

When a valid CC Network user profile URI is specified as the '''sioc:has_owner''', the resulting RDFa graph will look like the following:

<pre>
<http://example.com/> <sioc:has_owner> <https://creativecommons.net/johndoig/>
<https://creativecommons.net/username/> <sioc:name> "Username"
<https://creativecommons.net/username/> <sioc:member_of> <https://creativecommons.net/>
<https://creativecommons.net/> <dct:title> "CC Network"
<https://creativecommons.net/> <sioc_service:has_service> <https://creativecommons.net/r/lookup/>
<https://creativecommons.net/r/lookup/> <sioc_service_protocol> <http://wiki.creativecommons.org/work-lookup>
</pre>

In order for this graph to form, the URI '''https://creativecommons.net/username/''' must be a valid CC Network profile URI, and the user needs to have registered the work ('''http://example.com/''') with their account on the CC Network.

License Deeds (Metadata)

2011-02-16T01:21:54Z

John Doig: /* Work Registration */

Creative Commons license deeds will display information about the referring work if available. This page documents what information is displayed by the deeds.

== How it Works ==

When you visit a CC legal deed by clicking on a link from a licensed work, CC looks at the page you came from (the referrer) to see if it contains information about the licensed work. This information can include how the creator wants to be attributed, who identified a work as in the public domain, etc. If present, this information is displayed for the user, and used to generate copy and paste attribution/citation HTML.

=== Limitations ===

Works that require a password to access them can not be checked by the server software.

If the referring page contains multiple works under the same license (even with properly scoped metadata), we can not determine which link was clicked on. In that situation, we err on the side of certainty and do not display the information.

If the software can not unambiguously determine the title or attribution information, we err on the side of certainty and do not display the information.

== Features ==

The Creative Commons License Deeds will provide extra information about the referrer in three general categories:
* How to attribute/cite the work
* Work registration details
* Where to read more permissions assigned to the work

=== Work Attribution / Citation ===

The standard Creative Commons License Class Deeds(all non-Public Domain licenses) will display a notice instructing how the referrer must be attributed and generate an HTML+RDFa marking that can be used to attribute the work when sufficient metadata is available on the referring page. The Public Domain Deed's provide similar functionality; an HTML+RDFa string that can be used as a citation for the referring work in the Public Domain when sufficient metadata is available. The tables below describe which metadata triples must be available, and how each triple can affect the output seen on the deeds.

{{Infobox|This document contains prefixed identifiers for RDFa predicates, a table of these prefixes is presented at the bottom of this document. }}

=== Work Registration ===

In order for the license deeds to display information about a work's registration, there must exist a triple for '''sioc:has_owner'' on the referring document.

When a valid CC Network user profile URI is specified as the '''sioc:has_owner''', the resulting RDFa graph will look like the following:

<pre>
<http://example.com/> <sioc:has_owner> <https://creativecommons.net/johndoig/>
<https://creativecommons.net/username/> <sioc:name> "Username"
<https://creativecommons.net/username/> <sioc:member_of> <https://creativecommons.net/>
<https://creativecommons.net/> <dct:title> "CC Network"
<https://creativecommons.net/> <sioc_service:has_service> <https://creativecommons.net/r/lookup/>
<https://creativecommons.net/r/lookup/> <sioc_service_protocol> <http://wiki.creativecommons.org/work-lookup>
</pre>

In order for this graph to form, the URI '''https://creativecommons.net/username/''' must be a valid CC Network profile URI, and the user needs to have registered the work ('''http://example.com/''') with their account on the CC Network. When those two conditions are met, the license deeds will display a notice that reads:

<div style="background:#D4EFB9;padding:1em;">
[https://creativecommons.net/username/ Username] has registered [https://creativecommons.net/r/lookup?uri=http://lessig.org/blog/ this work] at the [https://creativecommons.net/ CC Network]

=== Work Registration ===

In order for the license deeds to display information about a work's registration, there must exist a triple for '''sioc:has_owner'' on the referring document.

When a valid CC Network user profile URI is specified as the '''sioc:has_owner''', the resulting RDFa graph will look like the following:

<pre>
<http://example.com/> <sioc:has_owner> <https://creativecommons.net/johndoig/>
<https://creativecommons.net/username/> <sioc:name> "Username"
<https://creativecommons.net/username/> <sioc:member_of> <https://creativecommons.net/>
<https://creativecommons.net/> <dct:title> "CC Network"
<https://creativecommons.net/> <sioc_service:has_service> <https://creativecommons.net/r/lookup/>
<https://creativecommons.net/r/lookup/> <sioc_service_protocol> <http://wiki.creativecommons.org/work-lookup>
</pre>

In order for this graph to form, the URI '''https://creativecommons.net/username/''' must be a valid CC Network profile URI, and the user needs to have registered the work ('''http://example.com/''') with their account on the CC Network. When those two conditions are met, the license deeds will display a notice that reads:

<div style="background:#D4EFB9;padding:1em;">
(Lessig)[https://creativecommons.net/lessig/] has registered (this work)[https://creativecommons.net/r/lookup?uri=http://lessig.org/blog/] at the (CC Network)[https://creativecommons.net/]
</div>

License Deeds (Metadata)

2011-02-16T01:15:32Z

John Doig: /* Work Attribution / Citation */

Creative Commons license deeds will display information about the referring work if available. This page documents what information is displayed by the deeds.

== How it Works ==

When you visit a CC legal deed by clicking on a link from a licensed work, CC looks at the page you came from (the referrer) to see if it contains information about the licensed work. This information can include how the creator wants to be attributed, who identified a work as in the public domain, etc. If present, this information is displayed for the user, and used to generate copy and paste attribution/citation HTML.

=== Limitations ===

Works that require a password to access them can not be checked by the server software.

If the referring page contains multiple works under the same license (even with properly scoped metadata), we can not determine which link was clicked on. In that situation, we err on the side of certainty and do not display the information.

If the software can not unambiguously determine the title or attribution information, we err on the side of certainty and do not display the information.

== Features ==

The Creative Commons License Deeds will provide extra information about the referrer in three general categories:
* How to attribute/cite the work
* Work registration details
* Where to read more permissions assigned to the work

=== Work Attribution / Citation ===

The standard Creative Commons License Class Deeds(all non-Public Domain licenses) will display a notice instructing how the referrer must be attributed and generate an HTML+RDFa marking that can be used to attribute the work when sufficient metadata is available on the referring page. The Public Domain Deed's provide similar functionality; an HTML+RDFa string that can be used as a citation for the referring work in the Public Domain when sufficient metadata is available. The tables below describe which metadata triples must be available, and how each triple can affect the output seen on the deeds.

{{Infobox|This document contains prefixed identifiers for RDFa predicates, a table of these prefixes is presented at the bottom of this document. }}

License Deeds (Metadata)

2011-02-16T00:31:31Z

John Doig: /* Public Domain */

Creative Commons license deeds will display information about the referring work if available. This page documents what information is displayed by the deeds.

== How it Works ==

When you visit a CC legal deed by clicking on a link from a licensed work, CC looks at the page you came from (the referrer) to see if it contains information about the licensed work. This information can include how the creator wants to be attributed, who identified a work as in the public domain, etc. If present, this information is displayed for the user, and used to generate copy and paste attribution/citation HTML.

=== Limitations ===

Works that require a password to access them can not be checked by the server software.

If the referring page contains multiple works under the same license (even with properly scoped metadata), we can not determine which link was clicked on. In that situation, we err on the side of certainty and do not display the information.

If the software can not unambiguously determine the title or attribution information, we err on the side of certainty and do not display the information.

== Features ==

The Creative Commons License Deeds will provide extra information about the referrer in three general categories:
* How to attribute/cite the work
* Work registration details
* Where to read more permissions assigned to the work

=== Work Attribution / Citation ===

The standard Creative Commons License Class Deeds(all non-Public Domain licenses) will display a notice instructing how the referrer must be attributed and generate an HTML+RDFa marking that can be used to attribute the work when sufficient metadata is available on the referring page. The Public Domain Deed's provide similar functionality; an HTML+RDFa string that can be used as a citation for the referring work in the Public Domain when sufficient metadata is available. The tables below describe which metadata triples must be available, and how each triple can affect the output seen on the deeds.

{{Infobox|This document contains prefixed identifiers for RDFa predicates, a table of these prefixes is presented at the bottom of this document. }}

License Deeds (Metadata)

2011-02-16T00:25:23Z

John Doig: /* Public Domain */

Creative Commons license deeds will display information about the referring work if available. This page documents what information is displayed by the deeds.

== How it Works ==

When you visit a CC legal deed by clicking on a link from a licensed work, CC looks at the page you came from (the referrer) to see if it contains information about the licensed work. This information can include how the creator wants to be attributed, who identified a work as in the public domain, etc. If present, this information is displayed for the user, and used to generate copy and paste attribution/citation HTML.

=== Limitations ===

Works that require a password to access them can not be checked by the server software.

If the referring page contains multiple works under the same license (even with properly scoped metadata), we can not determine which link was clicked on. In that situation, we err on the side of certainty and do not display the information.

If the software can not unambiguously determine the title or attribution information, we err on the side of certainty and do not display the information.

== Features ==

The Creative Commons License Deeds will provide extra information about the referrer in three general categories:
* How to attribute/cite the work
* Work registration details
* Where to read more permissions assigned to the work

=== Work Attribution / Citation ===

The standard Creative Commons License Class Deeds(all non-Public Domain licenses) will display a notice instructing how the referrer must be attributed and generate an HTML+RDFa marking that can be used to attribute the work when sufficient metadata is available on the referring page. The Public Domain Deed's provide similar functionality; an HTML+RDFa string that can be used as a citation for the referring work in the Public Domain when sufficient metadata is available. The tables below describe which metadata triples must be available, and how each triple can affect the output seen on the deeds.

{{Infobox|This document contains prefixed identifiers for RDFa predicates, a table of these prefixes is presented at the bottom of this document. }}

==== Standard Licenses ====

Supported RDFa Predicates (in order of precedence):
* '''Attribution Name''': cc:attributionName, foaf:name of dct:creator, foaf:name of dc:creator
* '''Attribution URL''': cc:attributionURL
* '''Title''': dct:title, dc:title

Assuming the referring URI is '''http://example.com/work''':
