Hello all, *The WikidataCon <https://www.wikidata.org/wiki/Wikidata:WikidataCon_2021>, the conference dedicated to the Wikidata community* and co-organized by Wikimedia Deutschland and Wiki Movimento Brasil, is taking place online on October 29-31, around the theme “a sustainable future for Wikidata”. In this update, we are very excited to share with you the first announcements about the program of the event! On October 29th, the first day of the conference, you will discover a *program of keynotes and round table discussions* carefully curated by the organizing team. Knowledge equity, Abstract Wikipedia, the technical challenges of the Query Service, and an overview on how Brazilian cultural institutions use Wikidata, are some of the topics that will be presented during this first day. We will also have various celebrations related to Wikidata’s anniversary that will allow us to celebrate achievements of the community and discover new projects. You can have an overview of the program of Day 1 here. <https://www.wikidata.org/wiki/Wikidata:WikidataCon_2021/Program/Day_1_-_Main_program> On the next two days of the conference, the program will be made of *presentations, discussions and workshops coming directly from the participants*. We will have several thematic tracks split during three time slots, to allow people from various time zones to attend. The content of these tracks will be proposed by the Wikidata community. This process will start at the beginning of October. More information will be added on this page in the next few weeks. To support us in running this very ambitious event, five organisations are sponsoring the WikidataCon. You will find a description of the sponsors here <https://www.wikidata.org/wiki/Wikidata:WikidataCon_2021/Organization/Sponsors>. Some of these organizations are already benefiting from the amazing content of Wikidata, and their contribution to the conference is one of the ways they can engage more with the community and support the future of the project. October is also the celebration of *Wikidata’s ninth anniversary*, as the project was officially started on October 29th, 2012. Every year, community members work together on birthday presents that will be showcased during the WikidataCon. You will find the ninth birthday page here <https://www.wikidata.org/wiki/Wikidata:Ninth_Birthday>, and you can already think about a birthday present you would like to prepare. Last but not least: the registration for the conference will start on September 15th. More information will be added on the Attend page <https://www.wikidata.org/wiki/Wikidata:WikidataCon_2021/Attend> at the time. Thanks for reading this update!
