Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
<button name="set_open" string="Re-open project" type="object">
<button name="set_open" string="Re-open project" type="action">
According to the type used at the button, the name varies.
For type="object", you need to define a method available at python and add it as name
def set_open(self,..)
For type="action", you need to specify which action you need to trigger, It may be any action (window action, server action, etc..)
name="%(action_view_sale_advance_payment_inv)d"
E.g. https://github.com/odoo/odoo/blob/8.0/addons/sale/sale_view.xml#L87-L88
For type="workflow", this triggers the worklfow transition whose signal is equal to name
