Peace
We took over the development of the Themenportal Friedensrepräsentationen for the Leibniz-Institut für Europäische Geschichte, building a light-weight solution enabling effortless maintenance and operations. Using WebWorkers, we were able to move all functionality to the browser: There is no backend application but the fully responsive page still privides a full text search feature covering thousands of records, also on mobile.

TEI XML with JavaScript?
The Philipps-Universität Marburg wanted us to do additional work on the ARCHITRAVE project: We started by fixing small bugs and adding a feature here and there. Over the course of a year, we ended up implementing a complete TEI-XML transformation & rendering engine in JavaScript. We also integrated a suitable map component to visualize the authors' travel trajectories.

Reaching for Atlantis
Bernhard Schirg needed solutions for visual storytelling in the field of Public History. One is a database for the stories behind objects, the other one a platform for long-reads about the stories behind landscapes. We built two static pages, which ... aren't that static after all.
The fully responsive platforms are based on jekyll and come packed with a powerful frontend search (including a full text index) and dynamic display for blog categories, news and events. The carefully designed and animated UI widgets guide the user through the fantastic material.
The team manages research data conveniently within a spreadsheet that generates user-friendly visualisations. The apps are currently hosted on one of our linux servers in Europe. The content will go online spring 2021.

Search! Fast!
The Centre de recherche du château de Versailles asked us to develop a search backend and interface for the ARCHITRAVE project and we built it for them: a lightweight react frontend on a eXist-db + elasticsearch JSON api. The search deals with the peculiarities of the French and German languages and in Markus Matoni's words:
The website design and the search are key components of the website and the result is impressive and tells its own tale
Our open source search component is now being integrated in other projects.

45TB
Sometimes, we don't develop new things. For the Lyons Lab at UCSD San Diego, we took care of procurement, assembly and configuration of a Synology storage array. The solution provides users with 45TB of net storage for microscopy images, secured with btrfs on raid6. With automatic compression set up, this should provide enough room for some time to come!

Portraits
In an effort to investigate the Holzhausen and Senckenberg family's legacy a team at the Kunstgeschichtliche Institut Frankfurt am Main cataloged a massive contemporary portrait collection with close to 5000 images. We helped with our servers, operations, support for the database software. ConedaKOR and data import/export.

Agile da Vinci
The prometheus – Das verteilte digitale Bildarchiv für Forschung & Lehre delivers thousands of art history images to their users per day. We started by raising the test coverage for their platform from 30% to over 90% while upgrading the platform from rails 2.0.2 to rails 5.1 and from ruby 1.8 to ruby 2.5. As always, we streamlined the deployment process by transitioning towards the twelve factor app. Development is now fluid from feature idea or bug report to code in production and user experience. Since March 2018, we keep providing consulting, software development and operations activities to the project.

Give a man a fish ...
We gave an online training with basics in Ruby programming, ActiveRecord mapping and an introduction to the ConedaKOR source code. Beyond showing language and framework features, we also integrated a hands-on workshop using a typical toolchain. The team of the project Interdisciplinary Dictionary of Classic Mayan now writes scripts to automate migrations, modifications and validations.

... really, just interface
The Herzog August Bibliothek Wolfenbüttel has tons of data and they want to share it! This time, their massive manuscript database was to receive an API. To integrate well with the existing platform, we implemented an eXist-db module to deliver metadata according to the OAI-PMH standard.

Bootstrapped!
The international research project ARCHITRAVE - Art and Architecture in Paris and Versailles in Accounts by Baroque-Era German Travellers needed a design implementation for its web presence. The bi-national French-German project aims at scrutinizing the content of six substantial German travel accounts dating from 1685 to 1723, the earliest hitherto known. Based on an excellent model by ulli neutzling designbuero, we built fully reusable design components with twitter bootstrap and with a lot of attention to detail.

Extended Video processing for KOR
By changing the way videos are handled by ConedaKOR, the software can now convert and render them in all major browsers and devices. Thank you ETH Zürich!

Don't we have that already?
To find duplicates within a database with over 150k images, we developed a convenient command line tool based on perceptual hashing and BK-trees for the DFK Paris. Image versions with different color space, format, dimensions, hue, saturation or contrast are well detected as duplicates. Fine tune it with a configurable distance threshold. Go give it a try: its fast and its open source!

Interface, just Interface
To deliver content via an API and without a fuss, the Marbach Weimar Wolfenbüttel Research Association wanted a OAI PMH Static Repository Gateway implementation and they got one. The app runs on PHP5, PHP7 as well as Debian 9 and Windows with XAMPP. It has a tidy web interface to show, add, remove and validate repositories. The code is open source and comes with a handy vagrant environment for future development.

DevOps for MWS
Based in Bonn, Germany, the Max Weber Stiftung hired us to improve the deployment for their Quellenportal. The 5 cloud servers run a highly automated debian 9. They host the app, test and demo instances and of course monitoring and analytics platforms. We also configured the app to enable one-step deployments, so that their team can showcase new features quickly.

ConedaKOR Browser Addon
The DFK Paris funded the development of a browser addon for ConedaKOR that makes importing wikidata items a breeze. It also enables immediate media upload for imported items and it is available via addons.mozilla.org and chrome.google.com. Need help with a ConedaKOR installation? Contact us!

Publication Database
Leibniz-IGB needed a revamp of their publication database for internal reporting. We used a lot of autocompletes and inline help to make the app an intuitive experience. Fork it on github!

OwnReality
Based on data within a legacy database system, we developed a search tool for the OwnReality project at the DFK Paris. Our widgets allow searching and filtering the project's data, visualize TEI encoded publications and they integrate seamlessly with the underlying website. Fork it on github or read a blog post about the project!
