Programming by E-mail: a Programming Environment for Novice Users Yoshinori Aoki and Hiroshi Maruyama IBM Research, Tokyo Research Laboratory. Abstract Web services are a remarkable technology in which the programming interfaces of Web-based services are provided as XML-based interfaces. Internet-ready information appliances are also being developed which allows us to control them via the Internet. Hence, we will soon be able to control various kinds of services through the Internet. Such services include transaction services such as payments, notifications of stock prices, and controlling air conditioners in the users’ homes. After such an environment has been created, it will be necessary needed to provide a programming environment with which end users can easily create their own services for themselves by combining such Web-based services. This paper proposes a novel programming environment which allows novice users to easily create programs by e-mail.. 1. 䈲䈛䉄䈮 ࠗࡦ࠲࡯ࡀ࠶࠻਄ߢឭଏߐࠇࠆⶄᢙߩࠨ࡯ࡆࠬࠍㅪ ៤ߐߖࠆ઀⚵ߺߣߒߡ‫ޔ‬Webࠨ࡯ࡆࠬ[1]߇ᵈ⋡ߐࠇ ߡ޿ࠆ‫ޕ‬Webࠨ࡯ࡆࠬߢߪ‫ࠬࡆ࡯ࠨޔ‬㑆ߢ߿ࠅขࠅ ߔࠆ࠺࡯࠲ߪXMLߢ⸥ㅀߐࠇ‫ޔ‬SOAP (Simple Object Access Protocol) [2]ࠍ↪޿ߡ੤឵ߐࠇࠆ‫ޕ‬SOAPߪ‫ޔ‬ HTTP╬ߩࡊࡠ࠻ࠦ࡞਄ߢേ૞ߔࠆ‫ౕޕ‬૕⊛ߥWeb. ࠨ࡯ࡆࠬߩ଀ߣߒߡߪ‫ޔ‬᳿ᷣߥߤߩ࠻࡜ࡦ࡚ࠩࠢࠪ ࡦࠨ࡯ࡆࠬ߆ࠄ‫ޔ‬ᩣଔߩㅢ⍮ࠨ࡯ࡆࠬߥߤ‫ޔ‬ᄙ᭽ߥ ᔕ↪߇⠨߃ࠄࠇࠆ‫ޕ‬ ߹ߚ‫ߦࠢ࡯ࡢ࠻࠶ࡀޔ‬ធ⛯น⢻ߥᖱႎኅ㔚߽޿ߊߟ ߆⵾ຠൻߐࠇ‫ࠍࡦࠦࠕࠛߢ↱⚻࠻࠶ࡀ࡯࠲ࡦࠗޔ‬೙ ᓮߒߚࠅ‫߇ߣߎࠆߔࠅߚߒ⹺⏕ࠍ⚂੍ߩࠝ࠺ࡆޔ‬น ⢻ߣߥߞߚ‫ޔߚ߹ޕ‬ᖱႎኅ㔚ࠍࡀ࠶࠻ࡢ࡯ࠢ⚻↱ߢ ೙ᓮߔࠆߚ߼ߩ઀᭽ࠍᮡḰൻߔࠆߚ߼‫ޔ‬Jini [3]‫ޔ‬. -1−105−.
