Hi John and all,
You elude to something that maybe we haven’t really considered – Validation takes more than technical skills, it takes a teacher/mentor/helper personality. Even if we create some great training for how to validate, it might not be enough to bring the ‘right’ kind of people. Just something that caught my attention in this conversation, =Russ From: john whelan [mailto:jwhelan0...@gmail.com] Sent: Friday, January 15, 2016 6:25 AM To: Yantisa Akhadi Cc: HOT Openstreetmap; Mikel Maron Subject: Re: [HOT] OSM Data Quality Assurance Curriculum Draft I currently do a fair amount of validation, I don't think we have enough validators and whilst iD knowledge is nice to have I don't see it as being essential. I accept that in some circumstances JOSM may not be practical and it is not an ideal tool for everyone but let me sit a new mapper down at a machine with JOSM set up with the building tool and give them a project about mapping buildings and I'll get five times more buildings out of them than I will in iD not only that but they'll be more accurately placed, squared and correctly tagged. For landuse=residential and highways again I don't see the area=yes, the zebra pedestrian crossings, the untagged ways, the crossing ways and the highways almost meet errors that I see all over the place from iD mappers. I also see fewer this last quarter got missed. If you get them to outline the landuse=residential but don't tag immediately and just tag them at the end I can get a lot more productivity out of them as well. OSM can be edited with a variety of tools, iD is fashionable this week it may not be next week. I think there is a different set of skills needed for validation and for teaching. Validation and giving feedback for new mappers takes time, typically I can map twice as much work as I'm validating in the same time. The only off set is occasionally I get new mapper who is accurate and will carry on to map a few hundred tiles and at a good level of data quality. You need lots of patience for validation, two who have tried it have expressed frustration at the way instructions and tutorials are ignored.

Probably it will be better if I add the context of why we work on this curriculum first. This curriculum is part of our strategy to improve OSM data quality, especially in Indonesia. In these past 4 years, we have trained more than 2,400 people all over Indonesia. Yet the training material largely focus on how to collect spatial data using OSM. There is little focus on quality assurance and validation, since it is hard to teach this material to people who just knew OSM. Another reason was if there is large scale disaster happened in Indonesia, we need pool of mappers as we also need pool of validators. It is true that some of these materials have been discussed in different platforms (learnosm, teachosm, and course.hotosm.org) and these platform have been a great contribution for us to work on the curriculum. At the same time we need to ensure that the training materials will be applicable in Indonesian context. Therefore we also develop Indonesian tagging standard as a reference. About the audience as specified in the docs, probably "Prerequisite" would be a better word. It is expected that validators would understand about iD so that they can guide new user on how to map faster and better in iD (eg. using shortcuts and how to add additional tags). The use of Overpass is recommended, but we think that it would help their work better. I believe that this curriculum is more act as a guide for validators rather than the rule that they should follow. The needs for validators also true in Indonesia, that is why we develop this curriculum and we are planning to use it in our upcoming training and hopefully would add more validators throughout the countries. Furthermore, we hope that this curriculum would not only applicable in Indonesia, but it can be useful for others as well. Again, much appreciated for your response.

Why do they need to know iD? Are you suggesting that only people who know everything such as overpass turbo whatever it is should be permitted to validate? We don't have enough validators in HOT at the moment how will this improve things?

We just finished the draft for the curriculum and we are looking for input from you. Here is the link to the document <https://docs.google.com/document/d/1MwXGir0quZgAtnParhBChjx3JehFcOUDwiK41kgDVA0/edit?usp=sharing> . Looking forward for your comments!
