Wikimedia Hackathon 2016/Program

Blog post: Wikimedia Hackathon finds in Jerusalem a fertile ground for experimentation
Summary of the activities and other issues related to the hackathon

Wikimedia Hackathon is a major event that brings together more than 150 developers from all around the world to improve the technological infrastructure of Wikipedia, particularly the MediaWiki platform on which it is based, and the Wikimedia code development. This is your opportunity to meet the Wikimedia tech community, learn about the technologies and projects that power Wikipedia and thousands of other MediaWiki based websites and propose or join a demo-able project to hack on during the event.
Developers new to Wikimedia and tech-curious editors are also welcome!
Just bring your laptop, ideas, and energy to contribute – we promise a great event, cool atmosphere and an inspiring venue!

All participants of Hackathon are expected to respect and abide by the Wikimedia Friendly Space Policy. Individuals not cooperating with this policy may be asked to leave the event.

Main Development Focus[edit]

The main goal of the hackathon is to complete Community Wishlist projects. We are putting together a list of recommended projects right now. If your work is related to one of these tasks please add the link.

We are also looking at projects with a special local relevance – see engaging developer communities for the Wikimedia Hackathon 2016. You are welcome to add your task.


The event will be held in the Hansen House, a historical hospital transformed to a new media and exhibition space in the tranquil heart of Jerusalem. Today the Hansen House is Center for Design, Media and Technology. The center includes exhibition spaces, an animation lab, theater performance space, a projection room, studios for visiting artists and the Graduate Programs of the Bezalel Academy of Arts and Design Jerusalem.

Attendance of the event itself is free (including meals and refreshments), but subject to approval. Accommodation costs are not included with registration, however if you would like to stay at the event hostel you can indicate your interest on the registration form and reimburse Wikimedia Israel for the cost.

Scholarship registration and general registration is closed.


The Post Hostel's reception

Accommodation for the hackathon will be at the Post Hostel, a newly opened, stylish urban hostel, with an eclectic and contemporary blend of design, culture, people and experiences, attracting a wide range of travelers from all corners of the world. (Local media about the venue here).

The Post Hostel is located at 23 Jaffa St., a central location with lots of nearby attractions.

The rooms are shared. There are 2-10 beds in a room, depending on its size. The rooms are very spacious and each includes at least one shower and one toilet.

A bed costs ₪200 per night (approx. US$50). The organizers can cover this cost for some participants, but not all (see Participation for more information). In any event, you can reserve a bed and settle the payment through the organizers (you do not have to contact the hostel directly).

If you do not want to stay at the hostel, there are several nearby hotels that we recommend. Please make a reservation directly at the following webpages:


We have arranged for regular transport between the hostel and the hackathon venue.

The organizers are making special arrangements to ensure swift and comfortable entrance through the Ben Gurion international airport. It is strongly recommended to arrive through this airport, and inform the organizers if you choose to arrive by land or through another airport. It is also recommended to inform the organizers if your flight has a connection (i.e. if it is not direct).

Air travel[edit]

Most international flights to Israel land at the Ben Gurion international airport (TLV, note that flights to this airport are listed as flights to Tel Aviv), situated about 40 km from Jerusalem. For the most part of the time, look for our volunteers in a Hackathon purple Shirt. They will greet you and direct you to your transportation to Jerusalem.
There is also an international service to Eilat's Ovda international airport (VDA) situated in southern Israel near the city of Eilat, about 300km from Jerusalem.

Ben Gurion international airport transfers[edit]

Jerusalem is served directly from Ben Gurion international airport. Transportation from the airport to Jerusalem is provided by the official shuttle, taxis and trains (although the train service to Jerusalem is currently slow and ineffective, see "Trains" section for more information). You can exchange your currency to NIS in one of the currency exchanges or by withdrawing NIS from one of the ATMs at the airport (usually cheaper, depending on your own bank commissions). This is essential to pay for your transportation.

Nesher Shuttle

Nesher shuttles operate regularly (24/7) between the airport and Jerusalem. The shuttle is a 10-seat van that departs when full, fare is ₪64 (~US$16) per person. To get to the shuttle departure point, after baggage collection go straight past Customs to the Arrivals hall. Exit the Arrivals hall through exit 01. Proceed to the road and turn left (following signage to Jerusalem shuttle). The shuttle will drop you off at your address of choice in Jerusalem. You can book Nesher shuttle on your way back to the airport by phone (+972-2-6257227). Reservations should be made at least 1 day in advance during office hours (for departures on Saturday night or Sunday morning-noon you should book no later than Friday at noon, after which reservation office is closed until Sunday morning). The shuttle will pick you up from your address of choice in Jerusalem, dropping at the airport's Terminal 3. Passengers that need to get to the airport's Terminal 1 will ask the driver to stop there in the beginning of the journey.


The official taxi dispatcher is located at Exit 03 (past the train station, which currently does not have a direct line to Jerusalem). If you are a group of 4 people you can hire a private taxi to/from the airport for roughly the same price of 4 people in the shuttle.


Train service to Jerusalem will be temporarily closed on March 21st-March 31st due to maintenance work.

Ovda international airport transfer[edit]

This airport is very distant from Jerusalem in comparison to Ben Gurion international airport, therefore prefer TLV if you can.


Bus 282 (operated by Egged) leaves Ovda airport to Eilat and is synchronized with the flight schedule. Fare is 25 NIS one way (42.5 NIS two-way, if you purchase the electronic public transportation card for 5 NIS at Ovda airport).
Getting off at Eilat's central bus station, you need to take a bus to Jerusalem (bus 444 from platform #6). There are four rides on normal working days (07:00, 10:00, 14:15 and 17:00), the schedule is different on Sunday, Friday and Saturday (check at Egged's website). It is highly recommended to reserve your tickets in advance, it could be that all the bus seats were sold in advance. Fare is 70 NIS one way, 112 NIS two-way.
More information about bus 282: Bus 282 on Egged's website.
Arriving in Jerusalem's central bus station, one could take a local bus or tram to get to his destination.


There is a shuttle service that offers transportation to your address of choice in Jerusalem for a fee of 35$ per person. See Eilat shuttle website.

Arrival to the airport before departure[edit]

You should arrive at the airport (this relates to both TLV and VDA) for check in at least 3 hours before departure, please bear this in mind when arranging your transportation from Jerusalem back to the airport.
For more information, see Ben Gurion international airport official website or Ovda international airport official website.

Travel by land[edit]

Israel has border crossings with Jordan and Egypt. If you are coming from Amman, Jordan - use King Hussein Bridge (known in Israel as "Allenby bridge") border crossing to cross into Israel. Once crossed to Israel, you can take the shuttle to Jerusalem (10-seat van, leaves when full, stops only outside of Damascus gate of the Old City of Jerusalem - from which you can take a tram) for 37 NIS. Another option is taking a taxi to Jerusalem (to your address of choice) for 120-150 NIS. Exchange to NIS at the official currency exchange in the Israeli terminal in order to pay for your transportation.
Traveling from Israel to Jordan via Allenby border crossing is more difficult. Jordan requires having a visa to Jordan in advance in order to enter Jordan via this point, and does not supply visa on arrival (stamp) to any country. The only exception is if you have arrived into Israel from Jordan using this border crossing, and your Jordanian visa (probably gained at Amman airport) is still valid, you are good to go.

Interesting APIs we can use[edit]

HPE Israel has provided some cool APIs by HavenOnDemand (link) that people can use to make cool addition to their apps during the Hackathon. API functionality includes speech recognition, text formatting and conversion, image recognition and OCR, text analysis (sentiment, etc.). HPE will bring a few experts in those APIs to help interested developers to get started.
