note: ini juga nulis emailnya tidak sempat tuntas terus, saya kirim sahaja , sudah saved sejak 15 Dec , khawatir malah akan saya discard mesej nya. intinya saya disini memberi alternatif beda dengan tujuan sama, kalau memang dasar mentok baru boleh pakai cara tradisional menggunakan tanda tanya itu (bukan REST dan not much friendly to google mimiking railers yg suka pada nyolot sama seasidenya smalltalk)
oke setelah membaca penjelasan anda di email yang lain saya menjadi faham dan ingin menjawab di dalam thread ini aja ya.

Sekarang setelah mengetahui keperluan apa aja yang ingin dipenuhi, maka terjemahkan dari perbendaharaan kata-kata orang bisnis itu ke spesifik domain yang sederhana, yang ada adalah products. jadi GET /products GET /products/top GET /products/:id/edit PUT /products/:id kemudian berangkat dari sini Anda tinggal tuliskan spec Anda sebelum Anda memulai coding.
