Accessing Canada's Open Data through APIs Lucia Costanzo MA, MSc, MLIS McLaughlin Library www.lib.uoguelph.ca Learning Objectives Getting Comfortable with APIs by: Understanding how APIs work Learn how APIs are used Gain experience using APIs Gears and Stickpeople: https://www.hrvoice.org/putting-diversity-to-work/coloured-gears/ McLaughlin Library www.lib.uoguelph.ca What is an API?

Application Program Interface A set of functions and procedures that allow the creation of applications which access the features or data of an operating system, application, or service. Oxford English Dictionary McLaughlin Library www.lib.uoguelph.ca What is an API? McLaughlin Library www.lib.uoguelph.ca What are the Benefits? Efficiency: data easily shared and distributed to various data consumers

Wider Reach: use and reuse of data globally Automation: data collection and cost reduction Leverage Govt Data: available to wider audience Integration: interact directly with current data source https://api-all-the-x.18f.gov/pages/benefits_of_apis/ Check Mark Button: http://www.clker.com/cliparts/l/n/a/E/b/t/check-mark-button-hi.png McLaughlin Library www.lib.uoguelph.ca What are the Disadvantages? Costly: expensive in terms of development time, maintaining API documentation and providing support to users of to implement API Security exposure: Adding an API adds another level of vulnerability to your website

McLaughlin Library www.lib.uoguelph.ca What are APIs used for? WorldCat is union catalog that itemizes the collections of 72,000 libraries in 170 countries and territories. APIs are used to: Search (to retrieve information about bibliographic holdings) Metadata (to retrieve and update bibliographic records) Primo API from ExLibris The main API method is making calls to retrieve information from Primo.

What are Web APIs? Web API Interface with URLs You send a request through the URL Server sends back content through response Types of Web APIs: SOAP - Simple Object Access Protocol REST or RESTful Representational State Transfer RPC Remote Procedure Call (Canada Open Data) Popular Tag: https://www.insurancejournal.com/app/uploads/2014/12/most-popular-sign-580x580.jpg McLaughlin Library www.lib.uoguelph.ca Common HTTP Verbs Indicate desired action to be performed for a given resource:

GET: Retrieve resource (most utilized) PUT: Create new resource POST: Update existing resource or create new resource DELETE: Remove resource Canada Open Data only allows for GET actions McLaughlin Library www.lib.uoguelph.ca APIs: The Basics URLs (the address of a World Wide Web page) can be used to make a request (API request or API call) URLs have parameters (similar to variables) Parameters specify things like:

How many results do you want back at once? How do you want the results to be sorted? What date range do you want to search? What location do you want to search? What format do you want the results in? https://schoolofdata.org/2013/11/18/web-apis-for-non-programmers/ McLaughlin Library www.lib.uoguelph.ca Lets get started!
