The document discusses the concept of mashups, which are web applications that combine data and code from various sources to enhance or create new services. It outlines the technical requirements for building mashups, examples of existing mashups, and the potential benefits for organizations, particularly in the context of libraries. The author highlights the growing availability of mashable content and APIs, encouraging experimentation with integrated web services to boost productivity and innovation.

2. Mashups are more than just:

3. Why Mashups?Low-cost/low-risk developmentRapid development cycleDo something fresh quicklyTypically do not require a huge amount of staff timeUtilize someone else’s computing power, i.e. “the cloud”More and more information service providers are enabling their content to be “mashable”Subscription content vendors“Free” Internet services

4. What is a Mashup?A web application that combine data and code from content sources out on the web to produce:Modest improvements to an existing web services (ex: embedded a list of relevant links from a third party service in an existing websites)An entirely new web applicationMashups are typically made up of both:Local ContentRemote ContentA mashup is composite web applicationCan be thought of as “Remixing the web”Presents the user with a new view or service built on top of existing data and servicesExecuted with lightweight web programming techniquesWeb servicesApplication Programming Interfaces (APIs)

5. What do you need to know (technically speaking)?Basic HTMLWidgets“<embed>” a service or dataRSS Collating and parsing feed data is an integral part of many mashupsMany “web services” return data as feedsBasic javascriptWork with simple APIs and XML as a data formatServer side scripting languagesAllows you to fully interface with APIs in your applicationIntegrate local and remote content on a complex scale

6. Who’s Doing It?Just about everyoneYahooMany servicesGoogleBook/MAPSAmazon Libraries and library content vendorsFederated search providers/designers (these maybe the original library mashup)Even the Library of Congress - http://id.loc.gov/authorities/

8. Web Services at OCLC

9. App Services at flickr

11. Or This? A Twitter Mashup

12. Which is possible because:Which brings you to RSS:Which is the basis for everything on the last slide

13. Mashup Building BlocksData that lives somewhere on the web and a good idea on what to do with itFeeds (RSS, Atom, RDF) are often the key ingredientWebsites as a service provide content in:XMLJSONCode that lives on the webApplication Programming Interfaces

14. Mashup LevelsBasicWidget Based MashupsIntermediateWorking with feedsWorking with a mashup aware editor (ex: Yahoo Pipes)AdvancedWorking with Web ServicesWorking with Application Programming Interfaces (APIs)Building your own web application

15. WidgetsThe Simplest Mashups

16. The Simplest MashupsWidgetsNo coding requiredCopy and pasteMay need security clearance to run remote javascript hosted on the widget providers web server

17. Explore Widgets at delicious

18. Widgetize Your Content

19. Copy and Paste<script type="text/javascript" src="http://feeds.delicious.com/v2/js/my.delicious.account?title=My%20Delicious%20Bookmarks&icon=m&count=5&sort=date&tags&extended&name&showadd"></script>Into the webpage of your choice

20. Embedded Delicious

21. Librarything WidgetsGet Your WidgetSelect Your Options

22. Slideshare

23. Which Can Give You:The WidgetEmbeddable CodeThis strategy works for youtube, google video, flickr, and most of the “social” web

24. Feed Based MashupsRepackaging and Repurposing Data

25. Feed-based MashupsGeneral strategy:Identify a bunch of feeds you want to keep track ofOrganize them or mine them for useful dataProcess them regularlyKeep track of when they failPresent the results back to your users

26. Basic Feed ContentRSS - http://feeds.delicious.com/v2/rss/ols.inside?count=15JSON - http://feeds.delicious.com/v2/json/ols.inside?count=15

27. Basic Example - Community Planet or the Feed of Feeds

28. Experiment with Feeds and Yahoo Pipes (http://pipes.yahoo.com)No coding requiredA good place to experiment with and identify a mashup strategy with little risk or effortClone the pipes of other users to get startedWhen you are done with your pipe you send the ouput to:

29. Pipes Interface – Sorting Pubmed Query FeedsDrag and Drop Programming

30. Pipe Results

31. Using Feeds in the LibraryUse feeds to aggregate search results from commonly used queriesCreate a bundle of search results important to your organizationsUse feeds to show new publications/titlesCombine with Amazon or Google Book search to add new contentUse feeds to aggregate organizational contentPull together bookmarking services of employeesPull together blogging content from employees

32. Pipes works with more than just Feeds: Data and Services

33. Web Services and APIsProgramming the Web

34. The API Building Block: A Restful Web TransactionFind a data source?Ask it a question in the form of a URL?http://myservice.com/?idrequest=myrequestcontentYou also have to answer: Am I eligible to get this data?Many APIs/Web Services require a developer or account ID to use hence:http://myservice.com/?id=mydevid&request=myrequestcontentGet data back in XML – often using AsychronousJasvascript and XML (AJAX)Parse data with your own local code or the api in questionPresent parsed data in your applicationResources with unique IDs work great in these sorts of transactionshttp://myservice.com/ISBNhttp://myarticleservice.com/pubmedid

35. Example: the Yahoo! SPELL Checking Web ServiceThe Question:The Answer:

36. Home for this Service

37. Where it might live? – Example DeploymentResponse from Yahoo!

39. Programming with APIsTypically simpleThe key is to fail gracefullyMake sure what the terms of usage areMany Vendors now Provide APIsIncluding:Most major social web services (flickr, LibraryThing)Most major web sources of “book” data (OCLC, Google Books, Amazon, Open Library)Many library software vendors (Examples - Ex Libris, Serials Solutions)

41. Query Worldcat via API

47. Mashup Wrap-UpThings to Remember about Mashups

48. Mashups and Content Management Systems?Is your current web content management system (CMS) mashup friendly?Open source CMS systems are ideal vehicles from which to explore mashups at a substantive levelWordpress, Drupal, Joomla, etc.All of the above have extensions that support many of the most popular mashup data formats, data providers, and apis

49. A Good Place to Start

50. Wordpress DashboardWordpress Delicious Widget

51. Mashup IssuesDependence on data or code that in some part you do not controlSecurity Policies can changeAccess policies can changeUsage limits on key-based apisLegal ImplicationsMake sure to read the terms of service for any service you expect to make publicMost non-commercial issues are fine

52. What can I do?See if your major information service providers:Provides feedsTry aggregating them in some useful fashionExperiment with <embed> options from services like Youtube or Slideshare in order to expand and highlight interesting organizational contentExperiment with the major social web services:Identify a “social” aspect in your organization that already existsSee if you can aggregate it and produce a useful new view of the dataCode your own mashup using apis

54. Are my services and data mashable?Does my own website provide feeds?Can my users <embed> content from our major services?Have we selected services and software that play well with mashups?

55. ConclusionsChoose web resources that are mashable when you canSupport for this is growing among web content providersMashups can:Cost little beyond staff timeBe fun and easy to createBe throwaway work that achieve substantial resultsAdd value in unexpected waysDevelop into essential services
