=Analytica Web Player=

The Analytica Web Player or AWP lets you make Analytica models easily accessible to anyone with a web browser. Users can open a model, view diagrams and objects, change input variables, and view results as tables and graphs via common web browser, such as Internet Explorer, Firefox, or Safari.  AWP offers several advantages over Analytica Player for distributing models:
* Users can review and run Analytica models without having to download or install any new software on their desktop -- they don't need to consult their IT department. You can invite model reviewers or users simply by emailing them the URL of a model in AWP.
* Model authors can be sure that end users are using the latest version of models and data posted on the server, without having to worry about distributing updates to users individually.
* By using password-protected AWP accounts, you can reduce the possibility that sensitive or proprietary models will be seen by unauthorized people. (You can also use the information hiding features of Analytica Enterpries to hide selected data or formulas.)


Model authors can upload models into AWP directly from their desktop. Users will also be able to save changed models, to revisit them in later sessions. Usually, AWP directories are password protected, so only authorized users can view and use models. But, we will also make a free AWP directory available for people who want to share their models openly.

We welcome your comments. Please tell us what you think, including how you would like to use AWP, and any additional features you would like.

== AWP is like the Analytica Player ==

AWP offers almost all the features of desktop Analytica Player. It lets you open a model, view diagrams, object windows, and results as graphs or tables. It lets you change any variable designated as an input, including as an Edit table; but it won't let you change other variables or create new objects. 

Soon, like the Power Player, it will let you save a changed model so you can continue with the changed model in a later session.

== How AWP improves on Analytica Player ==

AWP offers several enhancements that are not (yet) available in desktop Analytica:

* When you move the cursor over a node (without clicking), it highlights the node with a light rectangle around it. After a couple of second, it shows the description of the node (if it has one) in a popup balloon.
* Like most web applications, you use ''single'' not double clicks to drill down -- for example, to open a module diagram.
* It can display a result table or graph, or edit table, ''embedded'' in a diagram, instead of having to open the result or edit table in a separate window.  As model author in desktop Analytica, you simply make the height of the input or output node greater than four times the default size, i.e. 104 pixels (52 nodesize units). When you upload and open the model with AWP, the graph or table appears embedded in its parent diagram, in the rectangle with size and location specified for the node.
* It shows a copy button next to each result table, which lets you copy result values for pasting into Excel or other app.

== Other differences ==

===UI Differences===
AWP has a few differences from Analytica in its user interface:

* It only shows one window at a time (plus optionally an outline window on the left)
* A single click on a variable shows its ''result'', as a table or graph, not object window.
* It offers tabs across the top to show the parent diagram, object view, table, or graph for the selected object.
* The expandable Outline view shows only modules, not variables or other objects. You can switch off display of the Outline by [Fred please complete]

===Linked Modules/Libraries===

* If your Analytica model contains linked libraries or linked modules, you can still play it on AWP, but it may require some tweaking.
* The simplest solution is to convert the linked libraries and linked modules into embedded modules and embedded libraries. 
** To do this, e.g. for a linked module, bring up the object window for the linked module, then change the class from linked module to an embedded module.  Then save the model file, and upload it onto AWP.
* Another solution is to upload the linked modules and linked libraries onto the AWP server.  In this case, you need to be sure that linked modules and linked libraries are in the same directory as your model fie.  So when all the files are uploaded onto the server and the model file is opened, AWP will find and successfully load the linked modules and linked libraries.

== Features of Analytica not available in AWP ==

These features of Analytica Player are not (yet) available in AWP:
* Dialog boxes to change computation and display options, such as the Graph setup, Number format, Diagram and Node styles, Uncertainty Setup, and Preferences dialogs.  It uses whatever options and styles you chose in Analytica before uploading the model to AWP. 
* Slicer menus for multidimensional results that were introduced in Analytica 4.0.  E.g. Color key slicer, Symbol key slicer, Symbol Size Key slicer and bar origin slicer.
* Clickable references.
* It has limited ability to copy and paste a subset of values from and to a table, and no ability to copy diagrams and graphs (except if you use Snagit or a similar application for selecting material to copy).
* Other features which are new in Analytica 4.0/4.1 are being added to AWP.  If you see something missing that you would like to have, let us know.

== Features of AWP not available in Analytica ==
* You can stop AWP from displaying the outline tree. This is useful for a small model with only a few modules, or when you don't want users to look at all its details.  Here's how:
** With your model open in Analytica, create a new user-defined attribute called '''Awp_attrib'''.
** Open the Object window for the Model or top level module, and set its Awp_attrib to the value 'no_outline'.
** Save the model, upload it to AWP, and view it in AWP.
** Now it won't display the outline view.
* If you also want to prevent users from viewing the submodules of a model, add 'top_diagram_only' to its Awp_attrib:
** After doing the steps above to add the Awp_attrib, open the model in Analytica and view the object window for the top level model again.  
** Change the value of Awp_attrib to 'no_outline,top_diagram_only'. (Note you must have 'no_outline' as well as 'top_diagram_only' to make this work.)
** Save the model, upload it AWP again, and run it in AWP.  AWP users will now only be able to view the top model. Clicking on module nodes will have no effect.

== AWP access ==

=== A. Demo ===

* Run demonstration models posted by Lumina free.  This is a good way to experience how AWP works and get an idea of what's possible.

=== B. View Model by Invite ===

* If someone sends you an invite to view their model, click on the link to view their model.

=== C. Model Reviewer plan ===

* Post your own models so others can view and run them.
* Send email invites with web link to allow others to view your model.
* Up to 200 user sessions per month
* Each evaluation must complete within 60 CPU seconds.  
* $500/month or $5000/year subscription

=== D. Application Plan ===

* Post your model so others can view them.
* Send email invites to others to view your model
* Invite others with permission to view models and, optionally, save their own changes (coming soon)
* Up to 500 user sessions per month
* Each evaluation must complete within 120 CPU seconds.
* View model usage reports (coming soon)
* $1000/month or $10000/year subscription

== Enhancement requests==

* Do not show index selectors for tables and graphs. Currently, it only shows the selectors for 2D results, not the slicers for 3rd and higher dimensions anyway.  For most applications, the model author selects the best view, and showing these options to end user adds needless complication.


== AWP Attribute ==

When creating a model in Desktop Analytica you can add an attribute Awp_attrib which can be used to specify certain behaviors when the model is played in AWP.  [[AWP Attribute Values|Click here for more info.]]
