Hi Satoru-san, Thank you for your contribution. > Title and sub-title; > "Architecture and Requirements for Web-based Signage Player" agreed. > -- Core Feature > #I prefer 'feature' than 'profile'. OK. I know you don't agree to use the term "profile" for even the sub title. I don't stick with it. If you don't stick with the term "feature", let me propose another term. I'd like to make the sub title imply that each doc is a component of the "Architecture and Requirements for Web-based Signage Player". How about "module"? Core Module, Basic Media Module, etc. > Add a Concept chapter before Terminology; > Concept: I completely agree your draft of the concept chapter. I'll wait for other opinions for a few days, then I'll add the chapter before the terminology chapter if there are no objections from the other members. > Terminology chapter; > Items of Web-based signage, runtime and player are substituted with a concept chapter. I think it may be better to merge the terminology chapter and the concept chapter into one chapter as: "2. Concept of "Architecture and Requirements" and terminology Anyway, I'll try to put your draft into the doc.
