Importing, processing and exporting are done with *editable* nodes. It's easy to tweak your transformations since imported data remains intact and you can see results in a spreadsheet like UI.
REST API makes it possible to use GLAMpipe as a backend for data processing and storage tasks.
You can create new import, process and export nodes for your needs.
GLAMpipe nodes consists of small Javascript snippets. If you need to tweak these scripts, you can edit them directly inside your browser.
var hello_title = 'Hello world ' + context.doc['title'];
out.setter = {'new_title': hello_title};
result:
title | new_title ------------------ "Dog" | "Hello world Dog" "Tux" | "Hello world Tux"
With view nodes you can quickly create a faceted views for your data.
