  1. General concept about landing page seems to be right. More requirements in addition to collaborative mode, e.g. batch and scripting annotations, collaborative containers with out ownership (currently impossible on the server). Container could be marked as common, where everyone can import and manage it (chown, chgroup). Changes required to representation and accessibility of annotations in SPW. Utilization and best practices.
    • Chris is going to check what actions are needed to make adjustment in order to processing annotations in better way. Fixing problems with rendering def.
  2. Will got selenium tests working. He prepared few tests. Had problem with DB helper and loading right root account credentials. He started from group and experimenter tests.
    • Best practice in writing tests is to create new data in every tests or set up the data for the testing class.
    • Selenium test should cover only stable peace of application. Webadmin could be tested first because there are no planned changes. We will confirm priorities next week.
  3. Ola checked various techniques currently used in order to support high resolution images in web context #4026. General strategy for rendering high resolution images is mostly handled by bio-formats. Big image will be stored as raw data. At this moment it is possible to get portion of plane (done by Colin in #3782 duplicated for #3402). JPEG2000 compression is considered for each plane and building image pyramid.
    • Ola will implement fake mechanism in order to simulate tailing and play with viewer. We're going to meet on Tuesday morning to learn from the source code how current viewer works and how we possible modify it. Ola will try to prepare simple demo for next week.
    • Ola will talk to J-M how about his strategy for the Insight viewer.
  4. Will was playing with various techniques in order to draw shapes on top of image. He played with processing.js and found it useful in terns of visualization and drawing tool but not exactly sufficient and easy. He was also playing with jQuery drawing library such as cropping tool used already in webadmin and Raphael. It is important to test how those plugins behave with zooming. More in #3988
    • Will is going to prepare demo for next week.
  5. Clients reconciliation. Scott, J-M and Ola will do their best to seat together and define necessary clients layout changes. It is also important to prioritize that task, in order to distinguish trivial and large scale modifications.
    • Ola will respond to Scott while he is away this week and cc J-M.
