Last week the [Open Knowledge Festival](http://okfestival.org/) took place in Helsinki. Over 1000 participants from the world over took part in a week of workshops, hackdays and keynote addresses on all aspects of the open knowledge movement.
One of the major topic streams at the Festival was the [Open Cultural Heritage](http://okfestival.org/open-cultural-heritage/) stream that consisted of three days of activities bringing developers, open evangelists and digital humanists together for a series of talks, workshops and coding sprints.
[Net7](http://www.netseven.it/), leaders of DM2E Work Package 3, and the developers behind DM2E’s Digital Humanities tool stack which includes [Pundit](http://thepund.it/) and [Korbo](http://korbo.muruca.org/) were a key part of the three days of activities.
On Tuesday, Net7 led a session at the Cultural Hackday for building add-ons and extensions to Pundit, DM2E’s open-source semantic annotation tool.
First off the team created an add-on to Pundit that allowed for the visualisation of annotations using the [Edgemaps](http://mariandoerk.de/edgemaps/) visualisation engine.
Second the team integrated the new Europeana Linked Data API with Pundit, allowing users to easily refer to one or more of the 20 million metdata records [now made available under a the Creative Commons public domain dedication tool](https://blog.okfn.org/2012/09/17/the-revenge-of-the-yellow-milkmaid-cultural-heritage-institutions-open-up-dataset-of-20m-items/).
Net7 also had the opportunity to present a demo of their tool at the [OKFestival Open GLAM workshop](https://openglam.org/) working on top of digitised Finnish texts. [Open GLAM](https://openglam.org) is a component of the DM2E project aimed at encouraging more galleries, libraries, archives and museums to open up more of their digitised content and metdata for use in teaching and research.
