## Annotation Overview *Agenda* - Context - A starting point: Open Annotation Data Model - Some options for us - Annotator.js - Hypothes.is - Other things to look at - Challenges/questions that come to mind

## Context *Some background* - MIT faculty want Annotation for their courses; edx is not working on it (as far as we know) - I have some recent experience with annotation for the classroom via [Annotation Studio](http://rslt.hofstradrc.org/public/rslt-casey-v-secretary-of-health-and-human-services) - Lots of other groups are working on annotation for education, publishing, comments, social

## Open Annotation Data Model *Offers a fairly complete definition of Annotation* - [Motivations](http://www.w3.org/TR/annotation-model/#motivations) - [Simple Example](http://www.w3.org/TR/annotation-model/#introduction) - [Complete Example](http://www.w3.org/TR/annotation-model/#complete-example)

## Obvious options for us *Some existing tools we might build on/with* - Annotator (stable is 1.2.x; edge is 2.0) - Hypothes.is - Something else?

## [Annotator.js](http://annotatorjs.org/) *Text now, embeddable, plugin API, open source, in active development* - Wide adoption, real community of developers - Few dependencies, good tests - Highly customizable/extensible: it's a tool kit, with a plugin API, and some sane defaults - Version 2.0 is Alpha: no one's day job - Supports, or will support Open Annotation Data Model (W3C)

## [Hypothes.is](http://hypothes.is/) *Text and PDF now, embeddable, chrome plugin, open source, in active development* - Angular application with a Python backend - Good feature set out of the box: threading, identity, storage - Good tests - Serious engineering team (day jobs); might collaborate with us - Somewhat extensible, customizable - Supports, or will support Open Annotation Data Model (W3C)

## Other things to look at *At least for UX ideas.* - [NB](http://nb.mit.edu/): comments on images, open source, education, django, not readily embeddable - [Genius](http://genius.com/): web comments on text, for-profit, venture-funded, aggressive, rap-centric - [Point](http://www.getpoint.co/): web comments on text, chrome plugin/service - [Medium](https://medium.com/@dianakimball/close-at-hand-b4331294160d): web comments on text - [Quartz](http://qz.com/480741/t/268040): web comments on text - [Google Docs](https://docs.google.com/document/d/1DBfU2F9rM180pz9BI0gGitYP1ZdSUtY_-Nv2mrlk_vE/edit): document comments on text

## Some Challenges - Front end MVP *(highlights, comments, public/private, groups, sidebar, filtering?)* - Storage MVP *(support for MVP features, extensible for later features)* - Other target media types *(PDF, Image, Video, Audio, Other?)* - Other body media types *(Same)* - Other features *(user groups, search/filter/sort/collect, export, visualize, real-time)* - Other applications *(writing, discussion, peer review, grading, in-class discussion, flipped classroom)* - Interop with other systems *(via OA?)*
