My Guardian OpenPlatform API’n'Data Hacks’n'Mashups Roundup
Over the last week or two, I’ve put together a handful of hacks demonstrating how to do various mashup related things using the Guardian open data on Google spreadsheets, and the open platform content API. So here’s a quick summary – think of it as a single post mashup uncourse… ;-)
Just as way of background, here’s how the Guardian Open Platform was announced (I didn’t get an invite ;-)
So here’s what I’ve been up to:
- Using Many Eyes Wikified to Visualise Guardian Data Store Data on Google Docs: using a Guardian data in a particular Google docs spreadsheet, generate a URL that emits CSV formatted data from a specified region of cells in the spreadsheet and consume the live CSV data feed in Many Eyes wikified to visualise the data.
Nuggets: how to generate the URL for the CSV output from a Google spreadsheet over a range of specified cells, and then consume that data in Many Eyes Wikified. Use the Many Eyes wikified data as the basis for several Many Eyes wikified visualisations.
- Filtering Guardian Data Blog/Google Spreadsheet Data With Yahoo! Pipes: take a set of data regarding UK HE research funding from a Google spreadsheet via CSV into a Yahoo pipe, and then extract only those data rows that correspond to a particular result. Grab the CSV output from the pipe and pass it to Many Eyes wikified to visualise the research funding data for a single university.
Nuggets: how to use Yahoo pipes to filter CSV data to only pass through items from rows where the data in a particular column matches a given term.
- Creating Google Charts From CSV Data Inside a Yahoo Pipe: grab the CSV output from a Google spreadsheet into a Yahoo pipe, construct description elements for each feed item using data from several different columns in each CSV row, and then generate the URI for a call to the Google charts API using data from each row. By associated the chart URI with the appriopriate media group RSS attribute, a variety of widgets should be able to “play” the charts that are automatically generated from the spreadsheet data as a slideshow.
Nuggets: how to create Google Charts within a Yahoo pipe (using the Google Charts API) based on data pulled into the pipe from a CSV file generated from a Google spreadsheet.
- “JOIN”ing Data from the Guardian Data Store Student Satisfaction Data: pull data in from two different sheets on the same Google spreadsheet into Dabble DB, and generate another data table containing mashed together elements from the two spreadsheets. Display the result table via Many Eyes wikified.
Nuggets: how to use Dabble DB to “join” data from two separate tables that share a similar key column.
- Tinkering with the Guardian Content API – SerendipiTwitterNews: given a Twitter User id, pull the most recent tweets fro that user into a Yahoo pipe and run them though a term extractor; where terms are successfully extracted, use them as a query on the Guardian content API (either all articles, or just tech articles). The aim? Generate a news feed of items serendipitously related to your most recent tweets.
Nuggets: using the Yahoo term extractor on a Twitter feed to generate search queries over the content API; using API tags to narrow down the search to a particular topic area.
- Last Week’s Football Reports from the Guardian Content Store API (with a little dash of SPARQL): use a Yahoo pipe to pull football match reports “since last Saturday” from the content API, extract the name of the stadium each match was played in, and use as as the search term in a SPARQL query over a DBpedia page listing the locations of each English football stadium. Retrieve the lat/lon geo co-ordinates for each stadium from the SPARQL query, and associate them with the match reports. Plot the resulting feed of geo-annotated match reports on a Google map.
Nuggets: running a SPARQL query over DBPedia from a Yahoo pipe.
- Guardian Game Reviews – with Video Trailers: query the Guardian content API for game reviews from a Yahoo pipe, extract the title of each game and use it in another pipe that searches Youtube for a trailer (or review) of that game; create the URL of the actual Youtube movie file, and attach is as an enclosure URL to the output feed; view the result in a portable Grazr widget, which automatically embeds the Youtube videos in the widget.
Nuggets: using an embedded pipe block to search over Youtube; creating a feed that will auto render an embedded Youtube player when viewed in a Grazr widget.
So there you have it… my Guardian OpenPlatform hacks to date…
