MusicBrainz Summit / 11

This page has not been reviewed by our documentation team (more info).


MusicBrainz Summit 11 will happen in Rotterdam, Netherlands on October 15 - 17, 2011.

The main part of the summit will happen on October 15 and half of October 16. October 17 will focus on companies using or wishing to use the MusicBrainz data. Anyone is welcome to attend any portion of the summit, but October 15/16 will focus on general MusicBrainz topics and October 17 will focus on commercial aspects of MusicBrainz. Companies wishing to discuss how they use MusicBrainz should plan to attend on October 17.

Attendees should expect to arrive in Rotterdam in the afternoon/evening of October 14 and plan to depart in the afternoon/evening of October 16, unless you plan to stay for the October 17 portion of the summit as well.

Warp, Oliver and Rob will also be hacking on October 13/14. If you would like to hack with us, come join us. We'll be in Rotterdam starting on the 13th of October.

Session notes are now available.

Benthuizerstraat 60 | B, Apartment Fuchsia.

We've rented an apartment from October 13 - October 18. This will allow us to sleep 6 people (ruaok, ocharles, nikki, CatCat, reosarevok and navap) in the apartment (sadly only with 2 queen bed and a couch), but we have a kitchen and space for all of us to hang out and socialize for a long weekend.

When you arrive at the apartment, ring the bell for apartment B and we'll buzz you in. Be careful on the stairs, they are steep.

The apartment has a great internet connection; the WiFi password is posted over the flower photo above the table in the living room.


You'll need to be on this list if you're expecting MusicBrainz to take care of putting you up:

At Fuchsia

Fuchsia is full up, please don't make changes to this list:

Somewhere else (TBD)

We've got two rooms at the Hotel Hilton (they were having a sale!) for the following:

If you decide at the last minute to come and need a place to stay mail rob at musicbrainz snot borg ASAP.

Getting to Rotterdam

If you're flying to the Netherlands, make sure to fly only to Amsterdam Schiphol (AMS) -- from the airport you can take a train to Rotterdam Centraal, which only takes about 45 minutes. Flying directly to Rotterdam is quite expensive and will actually take longer than taking the train.

If you're planning to take Eurostar from the UK to Rotterdam, make sure to purchase two separate tickets. If you purchase one direct ticket via, you will pay much more than if you purchase tickets separately. Purchase your London <-> Brussels ticket from and your Brussels <-> Rotterdam ticket from . You will save nearly €400 in doing this.

Getting around in Rotterdam

To use public transport in Rotterdam you will have to get a so-called OV Chip Card. This is a contactless smart card, similar to the Oyster card in London. I recommend you buy an anonymous OV Chip Card at the airport or at Rotterdam Central Station when you arrive, this card will cost EUR 7.50. You will have to put some credit on it, EUR 10 is probably a good amount to start with if you're staying in Rotterdam for a few days.

Instead of an anonymous OV Chip Card you can also get a disposable card, you cannot put any new credit on these. These are probably not good value in many situations. Still, if you're only in Rotterdam for 1 day for example it might be more suitable, ask for more details on the exact offers when you arrive at the central station.

NOTE: When using the card, it is important to remember to check IN and OUT. EUR 4 is deducted from the card when you check in on the subway or a tram, this is the max amount a trip within Rotterdam can cost. When you check out the actual cost of your trip will be calculated, and whatever is left from those EUR 4 will be returned to your card.

The card will also work on proper trains, but will require a balance of EUR 20 on the card, so you're probably better off getting old style paper tickets for the train.
