Thanks @maning

We also have cases like this: image

If a contributor is unable to validate against additional/vicinity/local information, they can assume that the feature is correct. Which is possibly true, but there are instances they are not.

In this case, school share the same name as another school in the next city, but the DepEd data specified the village name that is verifiable against other data sources.

Later, to catch and resolve similar issues, data has to be validated in another pass against other reliable sources at the end of the OSMaPaaralan validation project.
