Mechanical Edits/Pipeliner

EARLY DRAFT

Rationale

The man_made=pipeline tagging scheme as of Dec.2014 introduced a change of the formerly used tag type=* to substance=*. The reason for this change is a potential conflict with type=* as used in relations. Also, type=* was considered a term too general.

This change requires the update of existing keys. To make the transition as smooth as possible, the following procedure is suggested:

• copy type=* of each object to substance=*
• wait a defined period to allow data consumers to update their software and rendering rules
• remove the old type=* tag
• re-run the mechanical edit script(s) for a certain period, to capture old tags that have been entered since the first / previous runs.

Copy Tag

Copy the value of type=* to substance=*

Object	Primary tag	Criteria
	man_made=pipeline	HAS type=* OR pipeline:type=* AND NOT substance=*
	pipeline=marker
	pipeline=substation
	pipeline=substation

Change Keys

During discussion of the proposal, the following keys have been renamed:

Primary tag	Old key	New key
man_made=pipeline	loop=*	flow_direction=*
pipeline=marker	mount=*	support=*

Transition Period

TBD: how to flag objects where the key should remain?

Manual Edit(s)

Due to the large number of currently existing substances, a manual update of the value is the best solution.

Checks

General Checks

Checks on pipeline & related objects to be performed independently of the mechanical edit:

• pipeline=marker not on
• for pipeline:ref=x : man_made=pipeline with ref=x has to exist
• combination of pipeline=marker and man_made=pipeline not allowed
• ...

Specific Checks

• both type and substance exist, but have different values
• ...

User Account

The OSM account Pipeliner will be used to run the scripts.

Anyone who is capable of implementing and running the scripts - step forward!
