Google Apps as a mashup environment

(Interaction and Display) Native Functions Google Apps Script APIs

Heavy lifting done by pre-existing applications or code libraries with each stage acting on naturally expressed representations of data from the preceding stage in the pipeline Mashups as pipelines…

Scripted integration of Google Apps

‘ We have a spreadsheet of OU broadcast campaigns – can you get them into a calendar?’

Google spreadsheet + Google Apps Script Into Google Calendar

Google Apps Script provides a way of working with representations that have a natural expression in a user facing application

Getting stuff in...

Creating a database on the fly…

Scraping multiple pages… var ss = SpreadsheetApp.getActiveSpreadsheet(); for ( page in pages ) ss.insertSheet( name( pages[ page ] ], 1 ); sheet = ss.getSheetByName( sname ); addTableImporter( sheet, I ) function addTableImporter( ss, n ) { var sc = ss.getActiveCell(); var c = []; c[0] = “=importHTML(‘”++”’) ; var arr = []; arr[ 0 ] = c; var destinationRange = ss.getRange( 1, 1, 1, 1 ); destinationRange.setValues( arr ); }
Obtain a list of page URLs to be scraped
Create a new sheet for each page using
Add an =importHTML formula with page URL to each new sheet
var ss = SpreadsheetApp.getActiveSpreadsheet() ss.insertSheet( sname ) sheet = ss.getSheetByName( sname );

Formulae

= googlelookup ("Brazil", "capital")

linked data Linked Data

= OUdata_courses ( coursecode , [ properties] )

function OUdata_courses(cc,props) { var args = _OUdata_SPARQL(‘courses’,cc,props) var sparqlResult = UrlFetchApp.fetch( 'http://data-gov.tw.rpi.edu/ws/sparqlproxy.php', {method: 'post', payload: args} ); return _handleSPARQLresult( sparqlResult ); }

Google Spreadsheets as a database

=QUERY('ISO Country Codes'!A2:B268, "select A,B where A contains 'FRANCE' limit 1")))

"Events, dear boy, events..."

...getting stuff out

The art of the mashup lies in breaking a problem down into a series of discrete functional steps, each of which can be handled by something that already exists.

Creating an effective mashup requires cunning, laziness, and a playful attitude…

… which is to say, a willingness to use as building blocks things that may not have originally been intended as such, such as Google Apps…
