The Jerusalem municipality is making an effort to publish data so that developers can do useful things with it. See details:
https://www.jerusalem.muni.il/Municipality/Pages/Transparencymuni.aspx
https://app.jerusalem.muni.il/#Registration
They also offer to look into publishing data which is not yet available on the site, if people ask for it and they are able to.
Is there any data in particular that we would like to use?
