文化遗产 -- 渐渐地被数字化,但难以被发现、
再利用、引用、交换、比较 ...
对一个图像而言,除了要求某一部分的选取、放大和缩小,
还有其它使用要求
移动设备的普及,使得使用者习惯于使用放大功能,细看某一部分。
对一个物件而言,往往会有多个图像
移动设备的普及,使得使用者习惯于使用放大功能,细看某一部分。
…使用者还希望对相同和相关的图像进行比
较,不管来源于同一处还是多处
多年来,大家都在采用不同的工具和系统,
独立王国,
贵、慢、功能简单、内容范围受局限;
难以交换、再利用、引用、比较
没有可认同的标准,我们只有独立王国
如果采用标准化的APIs,技术变得可
以互相交换,我们可以在使用层中对
不同技术进行选择
有了标准APIs后
Facilitate distributed access over standard APIs
内容变得可以分享

IIIF的两个API
Get images via a
simple, RESTful, web
service.
Support for tiles
needed for pan-zoom
viewers.
Just enough metadata to drive
a remote viewing experience.
(e.g. sequence, labels,
attribution, license)
Image API Presentation API
API= application programming interface, a set
of routines, protocols, and tools for building
software applications.

图像API 呈现API

Image request你要的是图像
的
• 哪一部分?
• 多大?
• 什么角度?
• 什么质量?
• 什么格式?
9
http://iiif.io/#try-itLet’s try it:
IIIF 的“图像API”能将这些要求通过统
一的句法来表现
根基URL
图像资
源
{根基}/{区域}/{大小}/{角度}/{质量}.{载体格式}

不仅仅是扫描的图像,3D物件的图像也可以这样表示

Partial Reconstruction of 1
Mirador viewer showing images from 16
institutions, each serving their own images
Mirado 显示器上展现由16个单位[不同]服
务器提供的某manuscript作品中某一页的图像
放大比较-可以细化到每个字母
Zoom to compare features from images provided by different
institutions – to the detail of the letter
b. 按需所求, 构造可互动的呈现界面,同时展示多种结果
mix overview images, descriptions, page views, detail views etc.
presentations
这种分享的canvas也可用于对不同博物馆的艺术作品、信件、展览、散文、相关作品、书目等的展示。
c. 用于将图中各部分的内容转成机器可读文字
d. 用于合作性的加注、修正、语义抽取
IIIF益处
1. 丰富多彩的图像递送
2. 可以用在原有系统上,服务器、客户端、插
件等
3. 出版一次,复用多次
4. 将众人提供的资源重新组合
5. 标注可由使用者进行
6. 全球性的支持和内容网络
7. 支持获取途径控制、归因
8. 促使由出处来源和受控的分享

Hinweis der Redaktion

  1. http://www.slideshare.net/azaroth42/introduction-to-iiif?related=2
  2. Allowing distributed access over standard APIs allows users to reuse and remix content, and supports an ecosystem of applications
  3. Strong IIIF community: national libraries, research institutions, museums, aggregators, projects
  4. The two APIs are: Image API and Presentation API
  5. Stanford University Libraries - Mirador demo http://showcase.iiif.io/viewer/mirador/ This demo of Mirador, developed by the Stanford University Libraries, allows the user to compare images from several different image repositories, including the Stanford Digital Repository, Yale University and Los Alamos National Labs.
  6. Again, back in the Mirador viewer we can see how collections and manifests relate to each other.
  7. 16 institutions – each serving their own image
  8. Zoom to compare features from images provided by different institutions – to the detail of the letter
  9. Create new interactive presentations that mix overview images, descriptions, page views, detail views etc.
