Adobe Digital Editions (abbreviated ADE) is an ebook reader software program from Adobe Systems, built initially (1.x version) using Adobe Flash. It is used for acquiring, managing, and reading eBooks, digital newspapers, and other digital publications. The software supports PDF, XHTML (through the nonproprietary EPUB file type specification) and Flash-based content. It implements a proprietary scheme of Digital Rights Management ("DRM") which, since the version 1.5 release in May 2008, allows document sharing among multiple devices and user authentication via an Adobe ID. ADE is a successor to Adobe eBook Reader. Windows and OS X versions of Adobe Digital Editions were released on June 19, 2007. Previous versions of the software required version 9.0 of Adobe Flash Player. Starting with version 2.0, however, which relies on .Net 3.5 on Windows, Flash Player is no longer supported. Adobe initiated development of a Linux version of ADE in 2007; however, this has not had any beta release or any formal updates.〔(【引用サイトリンク】 Adobe forum comments - When will linux version be released? )〕 ==Digital rights management== Adobe Digital Editions uses the proprietary ADEPT (Adobe Digital Experience Protection Technology) Digital Rights Management scheme,〔(【引用サイトリンク】title=Adobe Digital Editions 1.0 Press Release )〕 which is also implemented on some e-book readers, including iPads and many Android devices, but not Kindles.〔(【引用サイトリンク】title=Digital Editions supported devices )〕 The software locks content to up to six machines and allows the user to view the content on each of them. Barnes & Noble (B&N) ebooks are protected with a variant of ADEPT. In March 2009, the author of the reverse engineering blog ''i♥cabbages'' announced that they had broken the scheme. Adobe Digital Editions by default on Windows machines stores .pdf files of the documents in My Documents/My Digital Editions, where they can be copied and handled like other files, but they cannot be opened except with Adobe Digital Editions. Adobe's website has virtually no information on Adept except on its trademark page and a statement that OverDrive is compatible.〔(【引用サイトリンク】title=Partner Quotes )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Adobe Digital Editions」の詳細全文を読む スポンサード リンク
