MediaMosa...

�… is free, open source software to build a webserviceoriented media management and distribution platform.

A MediaMosa platform offers functionality for searching, playing, uploading, transcoding, as well as a fine granularity media access control system towards its users. MediaMosa is based on the Drupal framework and is designed to support content streaming applications by providing a back-end-, audio- and video-infrastructure.

�• Separation of frontend and backend functionality

�• Open source and open source components !

�• Based on a Service Oriented Architecture (SOA)

�• Multiple end-user applications on a centralized video backend infrastructure

�• Performance and High availability

�• Scalable for future expansions

�• Flexibility: combining components


MediaMosa ArchitectureCommon base for MediaMosa is Drupal:

Open Source Content Management SystemWeb Application Framework Modulair, Hook-oriented and Scaleable

Service Oriented Architecture (SOA)

REST on the outside, REST on the inside

Scalability, Redundancy, High Availability

Back-end


RESTRepresentational State Transfer

�• All interactions (messages) with the MediaMosa platform are done with REST-calls.

[GET] .../asset?limit=10<?xml version="1.0"?><response><header><item_count>8</item_count><item_count_total>8</item_count_total><item_offset>0</item_offset><request_process_time>0.0728</request_process_time><request_query_count>55</request_query_count><request_result>success</request_result>

<request_result_description></request_result_description><request_result_id>601</request_result_id><request_uri>[GET]

asset?limit=10&user_id=admin&is_app_admin=TRUE</request_uri><vpx_version>1.7.3</vpx_version></header><items><item id="1"><asset_id>ZG3SmyybQ61abezpbVHrJkFF</asset_id>

..... etc

�• REST strictly refers to a collection of network architecture principles which outline how resources are defined and addressed.

�• REST is a Client-server, Stateless, Cacheable and Layered protocol.

This reduces the complexity improves the effectiveness of performance tuningincreases the scalability of pure server components


Vorführender

REST Key Design Principles: Application state and functionality are abstracted into resources. Every resource is uniquely addressable using a universal syntax for use in web links. All resources share a uniform interface for the transfer of state between client and resource. Realworld REST:All static HTTP, Flickr, Amazon S3, most Yahoo! Services

WebservicesOver 150, divided in services for....

�• Play Video (PlayProxy HTML wrapper)

�• Authentication (DBUS for EUA)�• Authorization

(Domain, REALM, Group or mixed)�• Upload (PUT, POST, FTP)�• Transcoding�• Media Management: mediafiles,

assets and collections�• Search: Contextual Query

Language �• Jobs�• Metadata and OAI/PMH�• Notification�• Logging and Statistics
