Day Software has expanded its presence in the social media and open source markets with the acquisition of the founders and key innovators of Mindquarry, an open source collaborative software platform provider. Alexander Klimetschek, Alexander Saar and Lars Trieloff, experts in social media and collaboration, have joined Day's product development team.

The entrepreneurs' combined expertise in file sharing, task and content management, collaboration and social media technologies will enhance Day's product pipeline. In addition, the team's experience with Apache Jackrabbit, JCR (the Content Repository for Java Technology API standard), and open source platforms empower Day with additional resources for their ubiquitous ECM, WCM and DAM solutions.

Mindquarry is an open source collaborative software platform for file sharing (documents, images, media files, etc.), task and project management, team collaboration and Wiki editing. Prior to halting its commercial offering in October 2007, the company successfully meshed simplicity and functionality, enabling knowledge workers to connect with team members, impacting productivity through collaboration. Designed to combine integration and consultation services with an open source platform, Mindquarry was developed in Java and built upon a scalable REST architecture with AJAX and Web 2.0-style user interfaces.

Before joining the Day team, Alexander Klimetschek served as co-founder and chief architect for Mindquarry and is an expert in the Cocoon framework, REST architecture and modeling systems with FMC and User-Centered Design. He holds a master's degree in software systems engineering from the Hasso Plattner Institute. Also a Mindquarry co-founder, Lars Trieloff served as the company's COO and is a published luminary on DocBook-XML. He secured a master's degree in software systems engineering from the Hasso Plattner Institute. Alexander Saar served as the company's CTO, and managed systematic software development after founding Mindquarry with his colleagues Klimetschek and Trieloff. Saar also holds a master's degree in software engineering from the Hasso Plattner Institute.
