Hello
I am new to OSM and I am mapping a totally non-mapped area : Yemen (especially its capital Sanaa) where I currently leave.
Please someone have a look at what I did, and if you have comments, they are welcomed.

Firstly, I don't know the area at all so I can only comment in general. The streets join up at junctions which is good. The dual carriageway does not join at one end. There seems to be a lot of primary and secondary roads, which may be right, but you might like to read the wiki and come a decision about how the Yemen roads correspond to the highway settings. You might like to write this up in the Wiki for anyone else mapping Yemen to use and comment on. There are not many names on roads yet. Street names add great value to the map. Named streets can then (usually) be one OSM way. There a couple of ways that do not have a highway= tag so they don't yet show up.
Overall it is a great start and looks like a good base to grow on. Well done for starting in a blank area which can be daunting.

Welcome to the world of OSM.
I have looked at the area you have mapped and already OSM is now better than nearly all the current popular online maps! Google just has 5 roads converging to the centre of the city!
As Chillly has mentioned there does seem at first sight a lot of primary roads, however looking at satellite imagery the ring road does cover an area 5-6 kms across, so you probably have it right. Does Yemen have any road numbering/references which may help with road classification?
A read (and printout if possible) of map features on the OSM Wiki will help when first learning to map with OSM.
Just to comment on one node you have tagged, Tourism=bab al yemen, for example, you need to separate the name from what is being described, so from what I have looked up on the net, bab al yemen seems to be a tourist attraction (Yemen's Gate?), so I would have tagged it with one key/value Tourism=attraction and another key/value name=bab al yemen. The map feature list will help you how to tag things.
Another way to learn how things are done is to find a map of a well mapped city,
click on the edit tab, once the edit screen appears (potlatch), click on the play button (a red "practice mode" box should appear to the bottom right of the map, then click on the settings icon (tick in a box) and set the background to OSM - Osmarender from the drop down box. From then on you can click on different nodes and ways to see how they have been tagged.
Hope this helps. Well done for a great start and keep it coming. Have fun

Chillly, Netman, Rorym,
Thank you for your encouraging and useful comments.
Mapping in Yemen is not easy when knowing that :
- there is no road classification
- street naming is scarce and not really used. Some streets even have 2 or 3 names.
- a ring road around a city can be wider than the road connecting the two main cities of the country. Which one should be classified as a "primary rd". Is it based on its width, traffic, or importance in the network?
I have created a Yemen wiki page and will try to throw some ideas on how to classify roads. Can you please direct me to the wiki pages that would help me for that? I can not find them.
