Hi, Sirix.io is all about efficient versioning of your data. That is on the one hand it reduces the storage cost of storing a new revision during each transaction-commit while balancing read- and write-performance through a novel sliding snapshot algorithm and dynamic page compression. On the other hand Sirix supports easy query capabilities for instance to open a specific revision by a timestamp or revisions by a given timespan, to navigate to future or past versions of nodes in the tree-structure and so on. It basically never overwrites data and is heavily inspired by ZFS and Git and borrows some ideas and puts these to test on the sub-file level. In stark contrast to other approaches Sirix combines copy-on-write semantics with node-level versioning. It all started around 2006 as a university / Ph.D. project of Marc Kramis and I already spend my Bachelor's Thesis, Master's Thesis as well as several HiWi-Jobs on the project and I'm still more eager than ever to put forth the idea of a versioned, analytics plattform to perform analytical tasks based on current as well as the history of the data. I've been working a lot on Sirix.io the last couple of months and spent most evenings after my day to day software engineering Job. I had already posted around christmas, but now I've added a native JSON storage layer besides XML, that is the storage itself, XQuery extensions for JSON for joint XML- and JSON-querying, a RESTful-API also for JSON, added a website, a forum and first documentation... :-) and last night I release version 0.9.0. So, any feedback, comments, suggestions, just everything is more than welcome. I'll happily answer any questions you might have. kind regards Johannes https://sirix.io https://sirix.io https://github.com/sirixdb/sirix https://github.com/sirixdb/sirix
