Native Functions

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…

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

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 );}
1. Obtain a list of page URLs to be scraped
2. Create a new sheet for each page using
1. Add an =importHTML formula with page URL to each new sheet
var ss = SpreadsheetApp.getActiveSpreadsheet()ss.insertSheet( sname )sheet = ss.getSheetByName( sname );

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 );}

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…
