These migrations insert the merger change events that are needed for the 2025
municipality mergers.
The migrations executed by the `migrations` service insert the actual merger
change events for
- mergers where the resulting organisation is a new organisation (these were
added earlier in #442);
- mergers where the resulting organisation is an already existing, active
organisation; and
- the special case where the municipality Borsbeek is merging with the
municipality Antwerp, thereby creating a new district Borsbeek.
The migration executed by the `migrations-triggering-indexing` service updates
the status of the necessary organisations:
- the new municipalities/OCMWs/district are set from "Being founded" (nl. "In
oprichting") to "Active"
- the other municipalities are changed from "Active" to "Not active"
- organisations that simply remain active before and after the merger are *not*
updated
Set the end date for governing bodies for municipalities and OCMWs that are
involved in a municipality merger *and* will become inactive to 02 January 2025.
For the municipalities and OCMWs that remain active after the merger, the end
date has already been set previously.
As part of the 2025 municipality mergers 3 municipalities, and their
corresponding OCMWs, keep their original URI but do change their name. More
specifically:
- Bilzen becomes Bilzen-Hoeselt
- Ham becomes Tessenderlo-Ham
- Tongeren becomes Tongeren-Borgloon
It seems there were language tagged and non-languaged versions used
for the skos:notation from ADMS:identifier.
This migrations alings it, we don't want typed strings here.

A number of APBs were accidentally `org:linkedTo` all municipalities in
municipality and an APB for which:
- the APB is linked to more than 1 municipality; and
- the municipality does not match that of the APB's primary site.
The first condition avoids we remove `org:linkedTo` triples for APBs that were
created by the users, as these are only linked with a single municipality.
Originally the starting dates for the new governing bodies for the new
legislature was set to `2025-01-01` for all relevant municipalities, OCMWs,
districts, and provinces.
These migrations change that to more correct starting dates:
* For organisations that are **not** involved in mergers the new starting data
is `2024-12-02`, the first day installation meetings are allowed[1].
* For organisations that are involved in mergers the new starting date is
`2025-01-01`, the first work day of the new year on which the mergers take
effect. Note: this migration assumes there are no other start dates on
`2025-01-01`, so the migrations have to be run in the specified order.
