play along!

transforms the effectivities of socio-technical systems, making them work, or un-work, often in new and unexpected ways

hack (noun):

— Mark Olson (2013), "Hacking the humanities: Twenty-first-century literacies and the ‘becoming other' of the humanities".

Hacking the systems that construct and control access to our cultural collections is at the core of humanities practice in the early 21st century. As online collections continue to expand, we need to carve out spaces that resist the weight of scale and foster alternative perspectives. As interfaces grow in sophistication and complexity, we need to stage playful and pointed interventions that reveal their limits and empower critique. We do not all have to be coders, but we do have to take code seriously. We have to take what we are given by collection databases and change it.

GLAM hacking 101...

learn to read urls
look beneath the hood to see how things work
experiment (change things and see what happens)

reading urls

play with parameters
relationship between interface and urls
empty searches and hacking URLs

How many newspaper articles are in Trove?

go to Trove's newspapers
search for anything
delete your search term from the url
hit enter

web pages are never published

servers provide the blueprints, but your browser builds the page
you can inspect the blueprints to see how they work
you can intervene in the building process to change things

looking beneath the hood

View Page Source: the basic framework which might be overridden as resources load and scripts run
Developer Tools: live view of the current state of the page

right click on page
select Developer Tools > View Page Source

right click on page
select Developer Tools > Inspect

examine HTML code

check for errors

track what gets loaded

view styles

change some text
change some colours
swap an image

things to try

select an element to change

right click on the page element
select 'Developer tools > Inspect' to highlight the code
expand if necessary (click arrow)

change text

double click on the text to select it

edit the text

hit enter to update the page

much better!

change colors

select element
look for colours in the 'Styles' panel
click on the coloured squares to open colour picker
select a new colour

finding the source of page data

open the developer console
select the 'Network' tab
reload the page
look for data files

select a file to view details

click 'Response' to view contents

looks like metadata!

file url

look for data files

His work drew the attention of the Scottish Meteorological Society, which selected him to climb almost daily up to the summit of Ben Nevis to take meteorological observations. He won the Society’s Gold Medal for the continuous series of readings he made between 1 June and 14 October 1881. His wife, Leonora, made comparative observations at sea level at Fort William. In 1882 he had two assistants, William M. Whyte and Angus Rankin, who made the readings without him in 1883. During 1883 a special purpose-built observatory was constructed on the summit.

try opening urls
look for patterns in the url (eg identifiers)

item id

if you know the item id you can get data!

bookmarklets
userscripts (& userstyles)
extensions

changing websites

all ways of running javascript in your browser to change the content or behaviour of websites

bookmarklets

good for modifying urls
nothing to install
need to be initiated
Primo bookmarklets

is this image in Wikimedia Commons?

javascript:const nlsLinks=document.evaluate("//td[contains(., 'digital.nls.uk')]",document,null,XPathResult.ANY_TYPE,null),nlsLink=nlsLinks.iterateNext();window.open("https://commons.wikimedia.org/w/index.php?title=Special:LinkSearch&target="+nlsLink.textContent.replace("https://",""));

// Get digital item identifier
const nlsLinks = document.evaluate("//td[contains(., 'digital.nls.uk')]", document, null, XPathResult.ANY_TYPE, null);
const nlsLink = nlsLinks.iterateNext();

// Construct a search url, then open it
window.open("https://commons.wikimedia.org/w/index.php?title=Special:LinkSearch&target=" + nlsLink.textContent.replace("https://", ""));

create a bookmarklet to check

spaces and linebreaks removed or replaced

tells the browser to run this as code

javascript:const nlsLinks=document.evaluate("//td[contains(., 'digital.nls.uk')]",document,null,XPathResult.ANY_TYPE,null),nlsLink=nlsLinks.iterateNext();window.open("https://commons.wikimedia.org/w/index.php?title=Special:LinkSearch&target="+nlsLink.textContent.replace("https://",""));

add the bookmarklet to your browser

right click on Bookmarks bar, select 'Add bookmark'
give it a name
copy and paste the code into the url field
go here and click the bookmarklet to run it!

// Get digital item identifier
const nlsLinks = document.evaluate("//td[contains(., 'digital.nls.uk')]", document, null, XPathResult.ANY_TYPE, null);
const nlsLink = nlsLinks.iterateNext();

a common bookmarklet pattern

// Construct a search url, then open it
window.open("https://commons.wikimedia.org/w/index.php?title=Special:LinkSearch&target=" + nlsLink.textContent.replace("https://", ""));

extract a value from the page (eg an idenitifer)

construct a new url using the value and open it

userscripts

can change many aspects of a web page
need a userscript manager such as Tampermonkey
create/change userscripts using the built-in editor
install userscripts from sources such as GitHub
share your userscripts!
be aware of security risks

Tampermonkey is available as an extension or add on for most browsers, to install it:

go to the Tampermonkey home page
select your browser (Chrome / Firefox / Safari / Edge)
follow the link to your browser's app store
click on the button to install Tampermonkey

Note that if you're using Tampermonkey with Chrome-based browsers (including Edge and Vivaldi), you have to explicitly give it permission to run userscripts after installation.

add your own manifests

watch out for commas and quotes!

finding manifest urls

start in the digital gallery
click through to images
look for a IIIF Manifest link
if there's no manifest link look for a Universal Viewer link and open that
copy IIIF Manifest url
