Last week, from 1 to 5 October 2018, the third Gaia Data Processing and Analysis Consortium (DPAC) meeting was held in Abano Terme, Italy. This meeting was used to discuss the ongoing preparations for Gaia Data Release 3 and to reflect on Gaia Data Release 2.

This was only the third time DPAC members from all coordination units were brought together. This type of general meeting helps to understand the various interfaces the coordination units (CUs) and data processing centres (DPCs) have and brings together DPAC members who normally would not meet each other. DPAC members are working at various institutes across Europe and are often involved in one or two of the total of nine coordination units. 175 members attended the meeting of the total of about 415 DPAC members there are at the moment.

There were many fruitful discussions and inspiring ideas on how to tackle the issues one encounters when dealing with big data and the processing of big data using a distributed group of people. Looking back at data release 2 and the experience gained in this data release, the lessons learnt from the past data releases were used to create schedules for the development and processing for data release 3.

Next to a number of presentations given by the DPAC chair Anthony Brown, DPAC deputy chair Antonella Vallenari and Project Coordinator Gonzalo Gracia, plenty of splinters were organised to discuss and brainstorm on a variety of topics such as scientific interfaces, CU interfaces, archive architecture, user requirements (call for user scenarios is still open, give your input here), beta-testing, the validation of the data, the documentation, tools and outreach preparations for Gaia data release 3.

There was also time for some social events to help build team spirit and get to know one another. This year a quiz was organised on the history of astronomy by W. van Reeven. You can do this quiz yourself if you like, it is available for download here.
