Semantic Web Cube

The three sides of the tri-color cube in these logos evoke the triplet of the RDF model. The peeled back lid invites you to Open Your Data to the Semantic Web!

W3C anticipates using the Semantic Web cube in conjunction with other imagery related to the Semantic Web.

3. Usage

These policies were adopted on 2 November 2007 based on feedback from the community.

Semantic Web Logos and Technology Buttons that include "W3C"

Not-for-profit use is governed by the W3C Document License with the following exceptions:

For-profit use of these logos REQUIRES permission from W3C. Please send requests to w3t-pr@w3.org.

Semantic Web Cube alone and with "Semantic Web" (no W3C logo)

Use is governed by the W3C Document License with the following exceptions:

4. Frequently Asked Questions (FAQ)

Until now W3C has not had a high-level representation of the Semantic Web. Previous logos (such as the RDF logo) represented individual technologies. The new technology-specific buttons have been designed to be part of the Semantic Web brand. As we move forward, we are likely to create and use more specific imagery for some of the technologies that make up the Semantic web, e.g., for T-shirts or mugs. In that context, we are likely to use familiar blue RDF triple.

2. May I change the foreground and background colors of the text in the Technology buttons?

Yes.

3. May I change the cube colors?

If there is a "W3C" in the logo, no. Otherwise, yes.

4. May I change the size of all of the above logos?

Yes.

5. May I change the foreground or background color of the W3C logo?

No.

6. May I create a local copy of a Semantic Web logo or button?

Yes. If you make local copies, you should check periodically for updates from W3C (e.g., to account for small changes or new formats).

7. Why did you use the W3C Document License rather than a Creative Commons license?

Our goal is to allow certain types of derivative works (changes in size, colors) and to require attribution in a certain way (alt text or a specific URI). It is not clear from the Creative Commons Web site whether we can use a Creative Commons license to achieve this. On the one hand, we find, for example for "by-nd" this text: "You must attribute the work in the manner specified by the author or licensor (but not in any way that suggests that they endorse you or your use of the work)." However, in section 4(b) of the detailed licensing terms, we find: "The credit required by this Section 4(b) may be implemented in any reasonable manner;...." which seems to be in contradiction with (or at least more permissive than) the first assertion.

The W3C Document License is very similar to "by-nd", and adding a constraint on not-for-profit use is similar to "by-nc-nd." If we learn more and there turns out not to be a contradiction, we may also start to use the appropriate Creative Commons license in this policy.

8. What are the Pantone values for the three colors of the cube?
