Summary for the third board meeting

Summary for the third board meeting

Metatron Discovery’s 3rd monthly board meeting was held on December 17th at SKT-tower, Seoul. Metatron committers & stakeholders gathered together to discuss issues of discovery development and share news. We discussed about agendas below:

1. New release policy
2. Release history
3. Plan

New release policy

Versioning level changed

Recently, we decided to remove “hotfix” level number in our release versioning.

Branch policy changed

As many of others commented before, branch policy is also changed. Before today, we wanted to maintain our main branch “really” stable. But we notice that it doesn’t seem like any other open source project policies.

So it’s gonna be changed like below. Every feature updates is branching out from the master branch and merging to it. And for the new features, we cherry picks new features to the release branch. We are going to try different things for better development policy. Interests and advice are always welcome.

Release history

From 3.0.7 to 3.1.0 version of Metatron Discovery releases, we’ve made enourmous improvements. I just want to introduce you some of them.

Support Chinese in Metatron Discovery

As announced before, we support Chinese language in Metatron Discovery. Just change your browser language setting to use it.

Support geospatial data ingestion

Now metatron discovery support data ingestion to druid with indexing geo column. The druid register datastore and layers to Geoserver and it draws points to the map tiles.

Enhanced data preparation

The usability of the preprocessing feature has increased significantly during several releases this year. The ability to process multiple columns at the same time has also become convenient, and the ability to automatically generate rules by recognizing data sources has also been introduced. The preproduction will be further upgraded and will be introduced as a function that can be used by ordinary users next year.
