In large part due to Mozilla’s leadership over the years, the Open Web is in good health. Open standards and open formats are becoming the norm. This means anyone, anywhere can develop innovative applications that will work in any modern browser, without asking anyone for permission or paying any fees.* See Mitchell Baker (chair of the Mozilla board) on why Firefox is more than just a great browser.
Note that CC Search is no longer included by default in the Firefox search bar dropdown list. This is eminently reasonable from a user experience and business perspective, about which we’ll post more soon. If you want to add CC Search to your search bar, you can do so from the CC Search beta interface; feedback encouraged.
Congratulations and thank you to everyone at Mozilla and everyone who benefits from Mozilla’s work — that means all 2 billion people who currently have access to the net, and hopefully soon the 5 billion people who do not yet have access — understand why any barrier to participation is a barrier too high.
* Except where content and data are concerned; that’s where Creative Commons comes in. Today let’s celebrate the openness of the web at the standards/protocols/formats layer.3 Comments »
One of the questions people often ask about Open Educational Resources is “do they really increase efficiency?” Creative Commons has worked with many OER innovators, and their stories indicate that it does. We thought it would be useful to gather pointers to some of these examples. Please read on, and leave a comment with other great examples of how CC-enabled OER can increase efficiency for teachers, students and self-learners. Note of course that increasing efficiency is only one benefit of OER.
Negotiating permissions on the web
As a baseline, CC-licensed OER increase efficiency overall because it helps clarify user rights and responsibilities from the start. Copyright law rewards the authors of original works with a bundle of rights for a fixed period of time. Generally, a work cannot be shared or adapted without the permission of the rights holder (in the U.S., there are limitations and exceptions that temper the exclusive rights of the copyright holder–for example, fair use). Materials that remain under all rights reserved copyright require a potential user to ask permission first. The rights permissions process is usually long, difficult, and expensive. Solving the permissions problem is one reason Creative Commons came to exist in the first place–CC licenses let authors mark their creative works with the freedoms the creator wants it to carry. Creative Commons helps lower the transaction costs associated with using and sharing creativity on the Internet.
Even if educators want to share their teaching materials, if the rights are not clear to the end user, the resources will be used less, or not at all. To enable creative, innovative, and legal downstream use and remix of educational resources, clarity is essential. Creative Commons licenses are specifically designed to be easy to apply and simple for creators and users to understand.
The human-readable deed simplifies the terms of each license into a few universal icons and non-technical language, making it easy for teachers and students to understand right away how they can use the educational resource. The lawyer-readable legal text has been vetted by a global team of legal experts. The machine-readable code enables search and discovery of the educational content via search engines like Google, Yahoo!, and others.
Search and Discovery
The findability of quality educational content online is one of the fundamental challenges for teachers and students today. Properly licensed open educational resources can help users find content that they know they can use, customize, and reshare. Many existing search services integrate licensing information so users can filter for content that is licensed under Creative Commons licenses. CC licensing information is integrated with sites such as Google, Yahoo!, Flickr, Fotopedia, Jamendo, Blip.tv, Vimeo, Open Clip Art Library, and Wikimedia Commons. Other websites host (or point to) open educational resources–DiscoverEd, Connexions, CK-12, Flat World Knowledge, Curriki, OER Commons, and others.
Translations and Accessibility
OER can increase efficiency when materials are published under a license that permits the creation of derivative works (all Creative Commons licenses that do not contain the NoDerivaties (ND) condition allow this). OER can be translated into other languages and transformed into alternate formats–such as for display on mobile devices–more easily than materials published under all rights reserved copyright. MIT OpenCourseWare uses the Creative Commons Attribution-NonCommercial-ShareAlike license (BY-NC-SA). Nearly 800 MIT OCW courses have been translated into other languages, all without needing to ask permission from the copyright holder.
Bookshare is the world’s largest accessible online library for persons with print disabilities. Bookshare was awarded a grant by the U.S. Department of Education aimed at creating the first accessible versions of open digital textbooks. U.S. Copyright law permits some authorized entities to make accessible copies of books–and permits particular authorized disabled persons to access these vetted versions. This access is incredibly important, but the exception is limited, and does not apply for users outside of the United States. Open textbooks are low hanging fruit if they are released under a license that permits the creation of derivative works, because these can be more easily converted into accessible formats, such as audio and Braille refresh. No extra permissions costs have to be incurred or royalties paid for these adaptations to take place.
Customization and Affordability
OER can increase efficiency for teachers because they can be customized, easily updated, and oftentimes developed less expensively. Chuck Severance, a clinical professor at the University of Michigan’s School of Information, was able to publish a textbook in 11 days because he remixed an existing book. The remixed book Python for Informatics: Exploring Information, is a remix based on the openly licensed book Think Python: How to Think like a Computer Scientist. Students are able to take advantage of the University Library’s Espresso Book Machine to print on-demand copies for approximately $10. Python for Informatics is available under a Creative Commons Attribution-ShareAlike (BY-SA) license.
Education publisher Flat World Knowledge is a commercial textbook publisher that incorporates Creative Commons licensing into the core of their business model. Flat World Knowledge offers free and customizable online access to their textbooks, all available under a Creative Commons Attribution-NonCommercial-ShareAlike (BY-NC-SA) license. If users want a physical copy of the book, he or she can order it from Flat World, usually for under $50. Flat World Knowledge is competitive with traditional publishers from the get-go, hiring quality authors, peer-reviewing texts, and professionally editing content. Flat World Knowledge recently released information that 800 colleges will utilize their open textbooks this year, saving 150,000 students $12 million or more in textbook expenses. Affordability of educational materials, especially textbooks, is an increasing concern for students and their families. According to a widely-cited 2005 GAO report, college textbook prices have increased at twice the rate of inflation over the last 20 years; Student Public Interest Research Groups (PIRGs) suggest the increase is closer to 4X over roughly the same time period.
During the summer of 2007, the Virginia Department of Education realized their high school physics textbook wasn’t working – it was out of date and did not include information about state of the art scientific advancements. With various stakeholders from both the private and public sectors, the Secretaries of Technology and Education developed an open physics textbook under a Creative Commons Attribution-NonCommercial-ShareAlike (BY-NC-SA) license. The goals of the textbook development project were to provide all state physics teachers with up-to-date physics texts with emerging content, to create a database where content could be centrally located, to determine how the value of the textbook could be measured, and to decide whether the project was worth replicating for other subject areas. The book was developed and delivered to students within six months, 6 to 10 times faster than the 3 to 5 years officials were told would be necessary to develop a similar book under the traditional model.
The Internet and digital technologies have transformed how people learn. Educational resources are no longer static and scarce, but adaptable and widely available, allowing educational institutions, teachers, and learners to actively use, build upon, and share Open Educational Resources. OER enables teachers and students to find the content they know they can use, remix, and reshare–legally. OER helps address problems associated with language and accessibility, and empowers teachers to deliver customized, relevant content to learners, supporting individualized learning and student achievement. Engaging with the global OER community can help save time and money. These are just a few of the ways that Open Educational Resources helps increase efficiency. Please help us out by providing more examples in the comments, or add projects to our Case Studies.3 Comments »
yolink, “a next-generation search technology,” has added CC license support to its updated browser plugin. yolink’s browser plugin allows you to quickly scan your search results by specific key terms, effectively simplifying your more complex or advanced searches. Once you’ve found a relevant article, you can then share it with others via social media sites or a Google doc—all through the browser plugin window. The plugin has added CC license support, which means if you start a document with CC licensed site content the license will be retained and displayed in the doc.
For example, say I run a Google search on “Creative Commons”. Via the yolink browser plugin, I quickly scan the Google results for the Wikipedia article. If I want to start a Google doc with a particular passage, I don’t have to visit the Wikipedia page to manually copy and paste it—I can simply click on the check box next to the text I want and create a Google doc, all within the plugin window. yolink will automatically create a Google doc with the selected text and paste in the CC license info.

Today we’ve released a new CC content search interface on our Labs site for an initial live beta, testing some interface variations, before completely replacing our current search UI.
Why are we changing it?
Many of you use and love search.creativecommons.org, judging by actual use and tweets about the service.
After four years of the current tabbed interface, we have become increasingly aware of how many sites provide CC licensed content and would like to be included on CC Search. Due to the nature of tabs, there just isn’t room to easily showcase all these great sites. We’ve come a long way since our original selection of Google, Yahoo, and Flickr.
The current search embeds providers inside an iframe, which can be frustrating or confusing if you come to the site to find your favorite search providers wrapped in our frame.
I gave a brief presentation on the new search UI beta at a Creative Commons staff meeting recently. You can watch the UStream recording here.
Before we change the UI on search.creativecommons.org (also accessible via our home page and Firefox), we have some things to do: see how people use the beta, get feedback, and have the new interface translated into several languages.
Visit http://labs.creativecommons.org/demos/search, let us know what you think, tell your friends, and share it amongst your network.4 Comments »
Last week in the vuDAT building at Michigan State University, a group of developers interested in educational search and discovery got together to contribute code (in what’s commonly called a code sprint) to Creative Commons’ DiscoverEd project. Readers interested in the technical details about our work last week can find daily posts on CC Labs — Day 1, Day 2, and Day 3.
DiscoverEd is a semantic enhanced search prototype. What does that mean practically? Let’s say you’re a ninth grade biology teacher interested in finding education resources about cell organelles to hand out to students. How would you go about that?
If you’re web savvy, you might open up a search engine like Google, Yahoo, or Bing and search for “cell organelles”. You’d find a lot of resources (Google alone finds over 11 million pages!), but which do you choose to investigate further? It’s time consuming and difficult to sift through search results for resources that have certain properties you might be interested in, like being appropriate for 9th graders, being under a CC license that allows you to modify the resource and share changes, or being written in English or Spanish, for example. As you throw up your hands in dismay, you might think “Can’t someone do this for me?!”
DiscoverEd is an educational search prototype that does exactly that, by searching metadata about educational resources. It provides a way to sift through search results based on specific qualities like what license it’s under, the education level, or subject.
Compare search results for “cell organelles” in Google, Yahoo, Bing, and now in DiscoverEd. You can see that finding CC licensed educational resources is friendlier because of the available metadata accompanying each result.
While most search engines rely solely on algorithmic analyses of resources, DiscoverEd can incorporate data provided by the resource publisher or curator. As long as curators and publishers follow some basic standards, metadata can be consumed and displayed by DiscoverEd. These formats (e.g. RDFa) allow otherwise unrelated educational projects, curators, and repositories to express facts about their resources in the same format so that tools (like DiscoverEd) can use that data for useful purposes (like search and discovery).
Creative Commons believes an open web following open standards leads to better outcomes for everyone. Our vision for the web is that everyone following interoperable standards, whether they be legal standards like the CC licenses or technical standards like CC REL and RDFa, will result in a platform that enables social and technical innovation in the same way that HTTP and HTML enabled change. DiscoverEd is a project that allows us to explore ways to improve search for OER, and simultaneously demonstrate the utility of structured data.
Continued development of DiscoverEd is supported by the AgShare project, funded by a grant from The Gates Foundation. Creative Commons thanks MSU, vuDAT, MSU Global, and the participants in the DiscoverEd sprint last week for their support.1 Comment »
One of the issues that comes up repeatedly when talking about open educational resources (OER) is search and discovery. CC licenses provide the legal basis for sharing OER, but there’s a large technical component to sharing, as well. Publishers want to make sure their work is visible to users, and learners or educators need to be able to find resources relevant to the subject they’re interested in. Too often web scale search engines don’t do suffice: the amount of OER compared to the entire web is small, so the information you’re actually looking for is lost in the flood.
Last summer, CC, supported by Open Society Institute, organized a meeting of individuals working with OER repositories and tools to discuss the state of search and discovery for OER. There are many efforts under way looking at this issue, and the purpose of the meeting was to examine how these efforts can be made interoperable. For example, some countries are building national repositories, where the answer to the question is “put your OER in this big box”, while others — including Creative Commons, through our prototype DiscoverEd — are focusing on indexing a subset of the web, and trying to make results more relevant. We wanted to talk about how these different approaches can work together, so that consumers are able to find the resources they’re seeking, no matter where they’re located on the web.
What we discovered is that regardless of the approach being taken to solve the search issue, there are certain things that could be identified as best practices for publishers. We’ve pulled these together as an initial outcome from the meeting: Towards a Global Infrastructure For Sharing Learning Resources. As the title implies, this is the first step to building the interoperability needed to make OER discoverable. We’re going to be continuing examining these issues as part of the AgShare project, among others. If you want to keep up with that work as it develops, you can subscribe to the oer-discovery mailing list.3 Comments »
In July, CC Learn officially launched DiscoverEd, a search prototype that provides scalable search and discovery for educational resources on the web. We blogged about it again during Back to School week, emphasizing the future of search and discovery of educational resources and how we hoped DiscoverEd would catalyze efforts in that direction. Since then, we have been working with various organizations and projects who want to include their resources into DiscoverEd, and through all the back and forth about feeds and mark-up–essentially what’s required to get your stuff included for greater discovery–we realized we could streamline the process by putting some necessary information into a brief document.
Preparing Your Educational Resources for DiscoverEd is second in the CC Learn Step by Step Guides series, which is part of our larger Productions schema. It is a basic guide for those interested in preparing their resources for inclusion into search engines like DiscoverEd that utilize structured data. It is targeted at people or institutions interested in making their digitally published educational resources more discoverable. Though the document contains technical language and sample XHTML and RDFa, it’s really not all too complicated. Basically, you just need one of the right feeds to start, which you can then copy and paste the link of into ODEPO (the Open Database of Educational Projects and Organizations). ODEPO is hosted on OpenED, the community site for open education. It’s a wiki, so anyone can create an account and add their project or organization to the database.
But the guide explains all that, (as does the DiscoverEd FAQ) and the alternatives–which include contacting us directly. DiscoverEd already pulls from a number of institutions and repositories, and as it expands we hope to improve its search capabilities. Any feedback is welcome.No Comments »
Last year, we demoed DiscoverEd along with ODEPO at the Open Education Conference in Logan, Utah. CTO Nathan Yergler explained its various features and some if its issues. Since then, it’s been worked on extensively and some of its functionality has improved. We’ve even gone ahead and produced a white paper, which explains what DiscoverEd is, what it aims to do, and what you can do to help improve it.
With the production of this white paper, we would like to officially announce the launch of DiscoverEd. Entirely open source, DiscoverEd is an experimental project from ccLearn which attempts to provide scalable search and discovery for educational resources on the web. Metadata, including the license and subject information available, are exposed in the result set.
As noted above, DiscoverEd has been discussed at a few meetings already, so this launch is mainly to help spread the word and to spark additional conversation. If you are an educator or anyone else looking for educational resources, it is available for immediate use and we welcome your feedback.
We want to emphasize that DiscoverEd is a prototype intended to explore how structured data may be used to enhance the search experience. We are by no means launching this as a definitive tool; in fact, we intend just the opposite. We are launching this so that others in the search and discovery space can contribute to this project. There are a number of known issues which we would love help on, especially since we think the community’s input and work should go into shaping future versions of this tool. This tool is currently intended for educational resources, but there is no reason anyone can’t take and adapt it for other purposes.
Where do the search results come from?
Results come from institutional and third party repositories who have expended time and resources curating the metadata. These curators either create or aggregate educational resources and maintain information about them. If you’re a producer or curator of educational resources and would like to be included in the search contact us. If you’re an educator, we want to hear from you. What works for you? What’s broken? What can be improved?No Comments »
Google now enables CC-customized searching so you can search for Creative Commons-licensed content on either Google or Yahoo!’s Advanced Search page. Creative Commons’ own “Find” page now gives you to option to use either Google or Yahoo! for your searching. With two major search engines now enabling the dissemination of CC-licensed works, this enables greater dissemination of CC-licensed works and establishes CC’s licensing infrastructure as an important component of the Internet.3 Comments »
Six months ago we noted that one could use Yahoo!
link: searches to find Creative Commons licensed content out of 4.7 million indexed pages that linked to a Creative Commons license at that time.
Last month we mentioned that the Yahoo! search index contained over 10 million pages that link to a Creative Commons license.
Now we’re very happy that Yahoo! has built a Creative Commons search interface. As with our own search engine, you can limit results to works you can use commercially or that you can build upon or both.
We’ve added a box to our search engine’s results page that allows you to easily try a similar search at Yahoo! — try out this search for ‘shark’.
Read more on the Yahoo! Search blog, where the announcement of Yahoo! Search for Creative Commons features an inspiring guest post from Creative Commons chairperson Lawrence Lessig.
Way to go Yahoo!
