Lab Checking dead links

W3C Link Check 可以檢查 dead links, 而且只要輸入首頁, 就可以依據指定深度自動向下檢查, 而且也可以檢查對外連結(外站). Link Checker 首先要設定檢查深度(Check linked documents recursively, recursion depth=?), 如果沒有設定, 它就只有檢查首頁. 因此如果出現 deadlink, 就是在首頁. 如果你設定檢查深度, 它就會逐一檢查此深度內的每一頁, 在檢查某一頁開始時, 它會先顯示現正在檢查的 URL, 然後 在逐一爬行該頁內每個 link. 報表輸出很漂亮. 請參閱 http://validator.w3.org/checklink 請檢查三個你最常使用的網站, 看看連結的品質如何? 紀錄有錯誤連結 (HTTP Error 404) 的次數.

Web 2.0: hype or happiness?
Mary Zajicek
Pages: 35 - 39
Full text available: Pdf(290 KB)

Enabling an accessible web 2.0
Becky Gibson
Pages: 1 - 6
Full text available: Pdf(344 KB)

這兩篇文章有版權保護，必須在校內下載。或是透過圖書館線上登入，進行身分認證。

answer:

「Web 2.0」這個名詞，最先是由 O'Reilly Media創辦人暨執行長奧萊禮（Tim O'Reilly）提出，這些網站主要在幾方面有別於傳統網站：首先，他們朝思暮想的 再也不是如何賣「軟體」，而是「服務」，也就是把網站視為一個平台，「網站再也不純粹只是個『空間』， 而是一扇通往各式服務的『大門』，」以開發企業用Wiki軟體而聞名的Socialtext執行長梅菲德（Ross Mayfield）做了很貼切的說明；其次，「使用者」的角色將被置於最核心的位置，這些網站經營者開始學習「信任」，將生產、掌控資料的權力交還給使用 者，「由底層發聲」的部落格是最明顯的例子。

web accessibility（或稱網路無障礙）。其要旨在於確保任何人都有辦法取得放在網頁上的媒體內容 ── 無論人們是否遭遇了身體、心理或技術上的障礙，都不會妨礙人們接收作者所釋出的資訊。也就是讓網上的內容「易於親近」，易於取得、利用。
