With the last release 0.9.9 running nice and stable and the monthly updates to it contain mostly updated presets and imagery configurations, it is time to give you a preview of what I've been working on for 0.9.10.
Vespucci has long highlighted objects that had fixme tags and streets that are missing name tags, the code for this goes back to 2010, long before that was considered award worthy.
Over the years we have added support for warnings from Osmose and OSM Notes, making it easy to spot issues that might need work. In 0.9.9 I added preliminary support for highlighting objects that haven't been checked for a longer time.
But it is undoubtedly true that with OSM data becoming denser and denser and in many areas near complete it is non-trivial to find objects that need your attention..
The solution to this has two components:
A mode that only shows elements that have warnings.
And re-factored validation code that adds user configurable tests for missing tags and makes the resurvey warning time fully configurable (additional tests are easy to add in the new code and more will be added before release).
The missing tag check works together with the preset system, to generate a warning an object needs to be both missing the tag, and the matching preset needs to contain it too.
This means that if, for example, you want to highlight missing "name" tags you don't need to specify a long list of which objects really need that tag, it is enough that the preset suggests that a name tag should be added to the object.
This does have a slight downside in that the quality of the presets is key to this working well, and one of the reasons that the presets have received a lot of attention over the last couple of months (and that extends to JOSM too, see for example https://josm.openstreetmap.de/ticket/15143 ).
But the key point is that you can configure which keys you consider important and which not.
An early beta build of 0.9.10 is available https://drive.google.com/drive/folders/0B9pKLmh8s1h8bFI5bGd4VnhYWkk?usp=sharing a version signed with our release key will likely be available from google play store in one to two weeks.
Users that are receiving beta releases from the google play store should be getting the first beta release now. Release notes can be found on device and here.
