The document discusses mashups, which combine data from multiple sources to create new applications and visualizations. It describes various tools and techniques for building mashups, including APIs, data feeds, code libraries, GUI tools, and mashup platforms. The document also covers challenges with mashups and makes some predictions about the future of the mashup space.

Mashup University 4: Intro To Mashups
- 1. Cross Entropy Reduction for Image Analysis Using Simulated Annealing and Fast Artificial Neural Networks Mashup Camp IV, Mountain View CA
- 2. Introduction to Mashup Development John Herren Developer, Consultant, Masher-upper Mashup Camp IV, Mountain View CA
- 4. Wikipedia Says Mashup (music), a musical genre of songs that consist entirely of parts of other songs Mashup (video), a video that is edited from more than one source to appear as one Mashup (web application hybrid), a website or web application that combines content from more than one source
- 5. Do you have the mashup gene? Did you repurpose your toys as a kid? Do you still? LEGO maniac? Do you embrace the web as the ultimate maker's platform? Are you frustrated until you figure out how things work from the inside?
- 6. Do you have the mashup gene? Did you mourn the loss of Don Herbert?
- 7. Mashup Characteristics Combination Visualization Aggregation
- 8. Combination Use multiple data sources Join across dimensions Subject + Time/Place + ...
- 9. Combination Example Input: Bands I like + Where I live Data Sources: Eventful.com + Yahoo! music search Output: nifty mashup
- 10. Visualization Example ChicagoCrime.org
- 12. Aggregation Group your data and take a measure Sum, Avg, Min, Max Create information from the data Which becomes new data itself Use algorithms as a substitute for creativity! Classification, prediction, clustering, NLP Uncover hidden aspects of your data
- 14. Why Mashup? Perfect prototyping platform Hobby Business Embrace recursion Embrace recursion Profit! - Fulfill the underpants gnome prophecy
- 15. Step One Collect data sources. Use APIs to find Restaurant reviews Crime statistics Books about alpaca farming What's an API? Hotlinking 2.0?
- 16. Step Two Make a mashup (duh) Bootstrap a niche Exploit the long tail
- 17. Step Three Profit! 15 minutes of blogosphere fame Monetize traffic with ppc/cpm ads Affiliate programs Sell advanced features or memberships Sell it as software Early acquisition Your dream interview Win a Sun Microsystems 8-core 32GB RAM Sun Fire T2000 (insert liquidity event here)
- 18. Case Study Yahoo! News Tag Soup Yahoo! interviews Tagcloud.com Crazy press - Wired, TechCrunch Mashup Camp I Under the Radar Crazy Growth, VC’s Deadpool ?
- 19. The Mashup Pyramid GUI Tools Code Libraries APIs Data Feeds Platforms
- 20. Data Feeds RSS ATOM Demo
- 21. The Mashup Pyramid GUI Tools Code Libraries APIs Data Feeds Platforms
- 22. APIs Dynamic data feed Specific to the data service
- 23. Feeds How-to Two turntables and a microphone APIs and a scripting language Easy to prototype Easy to deploy Scripting language is rarely the bottleneck Two simple steps Request-Response* Iterate over response (result set)
- 24. Response Handling Usually XML SimpleXML: $rss->channel->item[0]->title; JSON Serialized Data $results = unserialize(file_get_contents($url)); YAML
- 25. SOAP Not really simple Not really object access Not really a protocol But there is hope
- 26. SOAP in PHP $client = new SoapClient("AmazonWebServices.wsdl"); $params = array( 'keyword' => 'alpacas', 'page' => 1, 'mode' => 'books', 'tag' => 'jhherren', 'devtag' => 'YOURAPIKEY'); $result = $client->KeywordSearchRequest($params);
- 27. XML-RPC Easier than SOAP Supports typing Uses system.methodSignature instead of WSDL Popular with blogging apps
- 28. REST Representational State Transfer Don't need extra layers URI as resource CRUD operations: GET, POST, PUT, DELETE Stateless, cacheable, layered (easier)
- 29. RSS Example In Python: import feedparser #by Mark Pilgrim rss_url = "http://feeds.feedburner.com/Techcrunch" feed = feedparser.parse(rss_url) for entry in feed.entries: print entry.title
- 30. AJAX & Browser-Side Asynchronous Javascript and XML a.k.a. XmlHttpRequest Client side XML, JSON, ...
- 31. The Mashup Pyramid GUI Tools Code Libraries APIs Data Feeds Platforms
- 32. Third-party Libraries & Frameworks Check the API providers first! Web Frameworks: Django, Ruby on Rails, Zend Framework Yahoo! code libraries Google AJAX Search API
- 33. Zend Framework Example <?php require_once 'Zend/Service/Flickr.php'; $flickr = new Zend_Service_Flickr('MY_API_KEY'); $results = $flickr->tagSearch("llama"); foreach ($results as $result) { echo $result->title . '<br />'; } ?>
- 34. The Mashup Pyramid GUI Tools Code Libraries APIs Data Feeds Platforms
- 35. GUI Mashup Tools Graphical widgets Boxely Adobe AIR SnapLogic
- 36. The Mashup Pyramid GUI Tools Code Libraries APIs Data Feeds Platforms
- 37. Mashups Platforms No server needed Graphical building tools Think MS Access for mashups Google Mashup Editor Yahoo! Pipes Boxely Popfly Dappr Kapow Facebook (you really have no excuse now)
- 38. Mashup Tools
- 39. Browser Based Authentication Login to the service, not the mashup Provides anonymity, but not safety Yahoo! BBAuth Google AuthSub
- 40. The Mashup Pyramid GUI Tools Code Libraries APIs Data Feeds Rich, Easy Flexible, Low-level Platforms
- 41. Pain Points Latency & Scalability API limits, abuse & metering API versioning IP, copyright, licensing Reliability & SLA Monetization Privacy, security, identity
- 42. My Predictions More mobile mashups More AI & datamining to supplement “user generated content” Microformats catch on and get aggregated OpenID catches on “ Attention Capital”, “Attention Management”
- 43. The Reality Twitter Facebook platform
- 44. New Predictions Increased competition among mashup platforms iPhone, iPhone, iPhone Microformat spam The big players will implement OpenID
- 45. Resources Programmable Web http://programmableweb.com/ Yahoo Developer Network http://developer.yahoo.com Google Code http://code.google.com
