improve browse and history "pages" by highlighting changes #1253

Open dieterdreist opened 8 years ago

dieterdreist commented 8 years ago

It would be convenient to show also summaries in object history and browse pages and highlight the kind of change, for example:

on browse pages:

for nodes+ways+rels:

amount of tags (useful for objects with lots of tags)

for ways:

amount of nodes

for rels:

amount of members (or nodes and ways and rels members)

in history:

generally

highlight the kind of action by formatting (similar to how it is already done for deleted objects in changesets): e.g. show new objects / tags bold (and or e.g. green) show deleted tags (that are in version n but not n+1) as strike through (and or red) in version n+1

for nodes+ways+rels:

amount of tags (useful for objects with lots of tags), separated into amount total+added+deleted (compared to previous version)

for nodes:

position changed?

for ways:

amount of nodes total,removed and added (compared to previous version)

for rels:

type changed (only displayed if yes, e.g. type changed from x to y) amount of node members total,removed and added (compared to previous version) amount of way members total,removed and added (compared to previous version) amount of role changes

see #738 http://osm.mapki.com/history/way.php?id=4239284 has a nice interface for that. Nobody is currently working on including such a thing in the main page.

Whilst useful, that's a bit "tech geeky" and I don't think it would really fit in the main page as is.

I'm also a bit reluctant to try and do even more analysis of the data because of the extra load it may add to the database - in some ways having these things done by third party services with their own copy of he data is better.

I've been meaning to put together a pull request that does a simple version of what I did with osm.mapki.com/history. Basically, to highlight what changed in the HTML of the osm.org history browse page.

It's good to know that others might find that useful, too. I'm happy to work with someone on that if there's interest.

@gravitystorm Would it make sense to close issues like this that have gone 1+ years with no activity?
