Ajaxinfo.com 駕馭 ajax 技術的風險管理系列文章，第二篇是在談〈運用 Ajax 技術的文化風險〉（Cultural Risk and Ajax）。從文化的角度，也就是所謂的：
By culture, we mean the sum of attitudes and behaviours that characterize a group of users. Cultural risk applies in varying degrees based on the variability of your audience. One of the differences between Amazon.com and Slashdot is the diversity of their audiences (Amazon being on the high end). When the audience is less diverse, it`s possible to take more liberties in the way you design the user interface.
...型塑著一群特定使用者的態度與行為的總合。文化風險這個概念根據你讀者型態的差異，可以依照不同的程度應用在你的讀者群之上。Amazon.com 與 slashdot 的明顯差異，就是他們網站讀者群的多樣性；Amazon.com 有較高的讀者多樣性。當讀者群比較集中時，你在設計使用者介面上的自由度就可以越大。
文化風險的來源有下列幾種：
1. 異質性的文化與期待
2. 使用者並不容易被訓練
3. 注意力頻寬有限
而降低文化風險的策略有下列幾點：
1. 進行 affordance 測試
2. 讓你的 ajax code 越輕巧越好
3. 把 ajax 視為一個提高附加價值的網站功能
4. 開放地運用視覺線索（visual cues）與 affordances
最終判定（verdict）上，請切記：這是一個創新的問題，並且是介於 google 的超強簡化介面與使用者所需要的複雜環境之間。記住運用 ajax 所可能犯的錯誤（Ajax Mistakes）。

Abstract. The management of multimedia documents, which includes storage, indexing, query optimization, and distribution, requires very strong frameworks and policies in order to ensure its efficiency and reliability. There has been much work done in the fields of databases, information retrieval, relevance evaluation, and transaction processing for any kind of data; but these four domains are too often considered separately. This definitely causes a lack of comprehensive distributed information management. We are convinced that much benefit can be obtained by apprehending a global vision of the whole management process through XML. In fact, we want to provide technologies that improve the access to heterogeneous and distributed sources of information for people sharing common interests. In order to deal with detailed and consistent information, we have to consider several layers of metadata related to users, communities, devices, and data sources. This categorized information has thereafter to be handled and efficiently used by applications combining processes from the four operative domains. Then, we claim that it is possible to offer users an appropriate viewpoint of the data, i.e. a personalized, effective, and very accurate access to the information.
摘要：多媒體文件的管理，包括儲存、索引、最佳化查詢與散佈，為了要確保它的有效性與可信度，需要非常強的架構與政策。在資料庫、資訊存取、相關性評估與交易處理的領域中，已經有了許多累積的成果；但是這四個領域常常被個別地考慮。這明確地導致了缺乏一種綜合性的分散式資訊管理。我們相信，透過 XML 針對完整的管理過程建立一個整體的視野會帶來很大的好處。事實上，我們想要提供為想要分享共同興趣的人們增進存取異質分散資訊來源的科技。為了要處理細節和一致的資訊，我們必須要考慮與設計和使用者、社群、設備以及資料來源的數層後設資料。經過分類過後的資訊於是被處理、並且有效率地被結合著來自四個運作領域程序的應用程式所使用。於是，我們宣稱：提供使用者一種對於資料的適當觀點；也就是說，一種個人化的、有效率，而且非常準確的存取資訊，是可能的。
