電子徽章規(guī)范:Mozilla Open Badgs解讀
發(fā)布時間：2019-01-07 12:49
【摘要】：電子徽章是近兩年伴隨開放資源運動、大規(guī)模在線開放課程等新型學習資源和學習模式出現(xiàn)的一種新型學習評估認證方式,具有高度的靈活性,可滿足各類學習方式的需要,有助于彌補傳統(tǒng)評價方式的不足。但是在電子徽章應用的初期,各種組織都在開發(fā)和應用自己的徽章體系,由此造成了徽章種類繁多、形狀不確定以及采用標準不統(tǒng)一等問題,使得電子徽章的可信度和可用度降低,推廣和應用變得困難。為解決這些問題,美國開源軟件組織Mozilla基金會啟動了Open Badge項目,以提供一個規(guī)范化的電子徽章創(chuàng)建、發(fā)布和認證技術架構(OBI)。OBI架構分為徽章獲得者、發(fā)布人、展示者三類角色,主要包括元數(shù)據(jù)規(guī)范、APIs、認證框架和徽章背包等模塊。利用OBI,任何學習者都可以從多個來源收集徽章,并統(tǒng)一保存和管理;徽章發(fā)行者和展示者也可以通過標準化的API、元數(shù)據(jù)規(guī)范以及統(tǒng)一的身份認證機制,制作和展示徽章。雖然OBI的開放標準取得了電子徽章方面很大的市場份額,但是在可信度、可靠性以及可驗證性等方面還需要繼續(xù)完善。未來的OBI將會在徽章展示、權限、接口等方面進行優(yōu)化,使其更貼近實際應用。
[Abstract]:Electronic badge is a new type of learning resources and learning model which appears in recent two years along with the open resources movement, large-scale online open courses and so on. It has high flexibility and can meet the needs of all kinds of learning methods. It is helpful to make up for the deficiency of traditional evaluation method. But in the early days of the use of electronic badges, organizations were developing and applying their own badge systems, resulting in a wide variety of badges, uncertainty in shape and inconsistent adoption of standards. It reduces the reliability and availability of electronic badges, and becomes difficult to popularize and apply. To address these problems, the Mozilla Foundation, an open source software organization in the United States, launched the Open Badge project to provide a standardized electronic badge creation, publishing and certification technology architecture (OBI). OBI architecture divided into badge winners, publishers, and publishers. Three types of role presenter, including metadata specification, APIs, authentication framework and badge backpack module. By using OBI, any learner can collect badges from multiple sources and store and manage them uniformly. Badges can also be made and displayed by standardized API, metadata specification and unified identity authentication mechanism. Although OBI's open standard has gained a large market share in electronic badges, it still needs to be improved in terms of credibility, reliability and verifiability. The future OBI will be optimized in badge display, permissions, interfaces and so on to make it closer to practical applications.
