Building a simple IIIF digital library with Tropy, Tropiiify and Canopy

Creating and maintaining an online digital collection can be a complex process involving multiple components, from organizational procedures to software solutions. With many moving parts, it's no surprise that building and curating a digital collection can be costly, time-consuming, and demanding to maintain. When dealing with cultural heritage, maintenance and long-term preservation should be our primary concerns. The approach we should always consider is minimal computing.

Revamping IIIF.link

A few years ago, I had developed a small application that allowed you to "frame" a specific part of an IIIF image and share it on the web through simple, concise URLs. But the initial version was rudimentary and only supported IIIF 2, I've since revamped it using the latest release of the TIFY viewer.

Anonymous webarchiving

Webarchiving activities, as any other activity where an HTTP client is involved, leave marks of their steps: the web server you are visiting or crawling will save your IP address in its logs (or even worse it can decide to ban your IP). This is usually not a problem, there are plenty of good reasons for a webserver to keep logs of its visitors.
But sometimes you may need to protect your own identity when you are visiting or saving something from a website, and there a lot of sensitive careers that need this protection: activists, journalist, political dissidents.
TOR has been invented for this, and today offer a good protection to browse anonymously the web.
Can we also archive the web through TOR?

Open BNI

Il 30 maggio 2016 viene annunciato il rilascio libero della Bibliografia Nazionale Italiana (BNI). Viene apprezzata l'apertura di questo catalogo (anche se con i limiti dei soli pdf), e da profano di biblioteconomia faccio anche una domanda sull'effettivo caso d'uso della BNI.
Il 30 agosto 2016 viene annunciato il rilascio delle annate 2015 e 2016 anche in formato UNIMARC e MARCXML.
Incuriosito dal catalogo inizio ad esplorarlo, per pensare a possibili trasformazioni (triple rdf) o arricchimenti con/verso altri dati (wikidata).

A wayback machine (pywb) on a cheap, shared host

For a long time the only free (I'm unaware of commercial ones) implementation of a web archival replay software has been the Wayback Machine (now Openwayback). It's a stable and mature software, with a strong community behind.
To use it you need to be confident with the deploy of a java web application; not so difficult, and documentation is exaustive.
But there is a new player in the game, pywb, developed by Ilya Kramer, a former Internet Archive developer.
Built in python, relatively simpler than wayback, and now used in a pro archiving project at Rhizome.

API json dell'opac SBN

Alcuni mesi fa è stata rilasciata da ICCU una app mobile per consultare l'OPAC SBN. Anche se graficamente poco accattivante l'app funziona bene, e trovo molto utili le funzioni di ricerca di un libro scansionando il codice a barre con la camera del telefonino, e la possibilità di bookmarkare dei preferiti.
Incuriosito dal funzionamento ho pensato di analizzarne il traffico http.
