About the project
FOODIE project aims at creating a platform hub on the cloud where spatial and non-spatial data related to
agricultural sector is available for agri-food stakeholders groups and interoperable. It will offer: an infrastructure
for the building of an interacting and collaborative network; the integration of existing open datasets related to
agriculture; data publication and data linking of external agriculture data sources, providing specific and high-
value applications and services for the support of planning and decision-making processes.
FOODIE project is addressed to four basic groups of users: a) stakeholders from the agriculture sector as end-
users of final applications, b) public sector for communication with farmers about taxation, subsidies and
regulation, c) researchers for large scale experimentation on real data and d) ICT companies for the
development of new applications for agriculture and food sector, mainly using implemented tools
FOODIE specifically works on three pilots:
 Pilot 1: Precision Viticulture (Spain) will focus on the appropriate management of the inherent
variability of crops,
 Pilot 2: Open Data for Strategic and Tactical Planning (Czech Republic) will focus on improving future
management of agricultural companies (farms) by introducing new tools and management methods,
 Pilot 3: Technology allows integration of logistics via service providers and farm management including
traceability (Germany).

Executive Summary
This document introduces the first prototypes of Advanced Rich Interfaces.

Library overview
The Advanced Rich Interfaces aim to provide the end user with the means to exploit data on an understandable and
user-friendly oriented way. To fulfil this task the idea is to provide an environment, based on FOODIE services, already
populated with general visualizations in which the creation and integration of new forms of data presentation for a
specific scenario will be reachable for third parties.
In order to reach this functionality, two approaches will be taken:
 The development of a web client dashboard, able to be configured to fit the end user needs and providing the
means to easily develop and integrate new visualization widgets more specific for a given use case.
 The development of a native android application, working both, as mobile visualization tool and as a demon-
strator on how to implement all the generic widget visualizations in a portable device and how to make use
of the FOODIE services.
Visualization Widgets and dashboard
The generic visualization dashboard stands with the idea of providing a tool to enable, given a specific use case, the
configuration of a set of visualizations fitting the exact needs of the end user. To support this target a dashboard and a
set of generic visualizations has been developed, all together being capable of defining which widgets are going to be
deployed and how they are connected between them.
Those end user needs may not be accomplished by generic visualizations, in some cases the requirement of specific
widgets could arise. For those scenarios, the dashboard architecture provides a specification on how to develop ad-
hoc visualizations which will be easily integrated in the dashboard.
Implementation
The visualization widgets and dashboard are being developed using ExtJS5[1] .
The dashboard provides:
 Possibility to select widgets to be shown on the visualization space.
 Input and specific configuration for each widget.
 Change the display position and size of the widgets.
 Add new widgets developed by others and integrate them in the dashboard.
The dashboard will be packaged as a WAR file to its future deployment in any different server.
For the Foodie project it will be deployed on JBoss web server and will be available at: http://foodie-
vm9.man.poznan.pl/FoodieVisualization/
Visualization widgets
There are already a set of widgets working which have been developed under the needs of the Spanish pilot Terras
Gauda. Those widgets are:
 Treatments: Widget to show a list of treatments (figure 1) and details of each of them (figure2). For each
treatment there are information about used product, worker, machine, quantity, treatment plan, plot, status
and date.

1 Treatment list widget
In the detailed view more extensive information can be found for a selected Item.
2 Treatment detail
 Treatment plans: Widget to show a list of existing treatment plans (figure 3) and details about each of them
(figure 4). For each treatment there will be information about the date, type of the treatment, products used
in the treatment and observations.

3 Treatment plan visualization
In the detail view there are more information about the selected treatment plan of the list. In this detailed view the
treatment plan can be edited.
4 Treatment plan detail
 Plot&Crops: Widget that shows a map with the polygons representing the available plots (figure 5) and the
crops of each plot (figure 6).

5 Crops visualization
6 Plots visualization
By clicking in each polygon the user can obtain information about the selected plot or crop. If the user clicks a plot the
the information that will be shown is name of the plot, type, identification code, area, and area of the specific polygon
in the case of a multipolygon plot (figure 8). If the user selects a crop, the information that will be shown is the plot
that owns the crop, and the species of the crop (figure 7) .

7 Crop detail
8 Plot detail
 Choropleth Widget: Widget that shows a choropleth map of the existing plots. The first step in the widget is
to configure it (figure 9). In this configuration window the user can define the property that will be evaluated
in each plot, and the colors and ranges that should be used in the map.
9 Choropleth Configuration

Once the widget is configured a map will be shown with each plot represented by the corresponding color. In the left
side, a legend will be shown explaining de meanings of each color (figure 10)
10 Choropleth Widget view
Widget configuration
Each time a widget is added to the dashboard, a configuration window will ask the user about some parameters that
must be fulfilled before render the widget. The first configuration (figure 11) asks the user about the title of the widg-
et, and the kind of input that it will use.
11 First widget config window
Depending on the type of input selected, a second window will be shown. At this time, there are only window for the
case of Web Service input, and the case of Event Input. If the user chooses Web Service input, a window asking for the
URL of the web service and the root property of the response will be shown (figure 12).

12 Web service config window
If the user chooses Widget output a different window will be shown. (figure 13) This window will contain the infor-
mation about the outputs of the existing widgets, which types correspond with the input of the new widget. So if the
user adds a widget that accepts tabular data, all the outputs of existing widgets with type tabular will be shown in the
config window. Then the user will select which outputs want to link as inputs for the new widget.
13 Widget output config window
After these configurations, the widget can add a last config window to be shown asking for widget-specific configura-
tion. An example of this configuration ca be seen in the figure 9

Widget development recommendations
Each Widget should have the following structures:
 The name of the Widget should be WidgetNameWidget (i.e. TableWidget, FormWidget, MapWidget, Time-
LineWidget). For the next steps, the words WidgetName will refer to WidgetNameWidget
 The base namespace for the classes of the widget must be Foodie.widgets.WidgetName (i.e. Food-
ie.widgets.TableWidget)
 The Widget must have a main view, which will be the view that will be use by the dashboard to show the
widget. This view must be named with the template WidgetNameMainView. Its fully qualified name should
be Foodie.widgets.WidgetName.view.main.WidgetNameMainView (i.e. Food-
ie.widgets.TableWidget.view.main.TableWidgetMainView).
 The XType of the main view must be WidgetName.
 The widget must implement a class with information about the widget. This class must be in the widget root
folder, and its name must use the template WidgetNameInfo (i.e. TableWidgetInfo), its qualified name must
be Foodie.widgets.WidgetName.WidgetNameInfo (i.e. Foodie.widgets.TableWidget.TableWidgetInfo). Its al-
ternateClassName must WidgetNameInfo. This class must be compliant with the following requirements:
o This info class must be a singleton class.
o This info class must have a property widgetName, which contains the human readable name of the
widget.
o This info class can contain a property named inputDataType, which will indicate to the system the
kinds of data that accept the widget as input. This property must be an array of strings.
 The different types of data have to be decided, but could be something like:
 record
 tabular
 data model related (plot, crop, treatment,…)
o This info class can contain a property named outputDataType, which will indicate to the system the
kinds of data that this widget will produce as an output. This is an array of objects that must have
the following structure:
 eventName: id of the event that will be used to output data from the widget
 dataType: type of data that will be sent through this event
 description: description of the event
 The widget can have an initial configuration view that will be shown just before the creation of the widget.
This view must be named with the template WidgetNameInitialConfigView. Its full qualified name should be
Foodie.widgets.WidgetName.view.config.WidgetNameInitialConfigView (i.e. Food-
ie.widgets.TableWidget.view.configTableWidgetInitialConfigView).
Also, if this initial configuration exists, there must be a view controller named WidgetNameInitialConfigView-
Controller. Its fully qualified name should be Food-
ie.widgets.WidgetName.view.config.WidgetNameInitialConfig ViewController (i.e. Food-
ie.widgets.TableWidget.view.config.TableWidgetInitial ConfigViewController). This view controller must have
implemented a class called getConfigData(), that return the configuration set in the configuration window.
The format of this object could be anyone, because it will be used internally by the widget.

 The dashboard will set some properties in the widget main view that will help the widget to integrate into the
dashboard. This properties are the following:
o widgetType: xtype of the widget.
o widgetInput: object containing the configuration of the input. The structure of this object will be the
following:
 type: type of the input. Can be “ws” (web service), “event”, “file” or “no”, if there is no in-
put.
 data: the input data. It depends of the type.
 WS
o urlWs: web service URL.
o root: root property in the json response.
 Event
o events: array with the events to subscribe. Each event should have the
following properties.
 eventId: id of the event
 eventType: type of the data served by the event
 widgetId: widget that will fire the event
 File: structure to be decided.
o widgetConfig: object containing the configuration of the widget. The widget developer decides the
structure of this object.
So, the basic folder structure for a widget will be the following:
- WidgetNameWidget
o WidgetNameWidgetInfo.js
o view
 WidgetNameMainView.js
 WidgetNameInitialConfigView.js (optional)
 WidgetNameInitialConfigViewController (optional, but mandatory if the configuration view
exists)
This structure defines the minimal requirements that the dashboard needs to be able to “understand” the widget.
Then, the widget developer could use every model, store, controller, view controller and view model that he would
need.
Native android application
Developed to implement the previous visualizations in native, usable mobile application, it also stands as a showcase
for the Spanish pilot showing how exploit FOODIE API to apply make use of visualizations in mobile devices.
Implementation
The application has been developed using the Android 5.0 Lollipop in order to cover natively a wide range of mobile
devices, providing the user with a better experience when navigating the visualizations. The functionalities have been
decided along with the Spanish pilot stakeholder and SERESCO.

4 Main menu
The features implemented in the application are:
 Annotations visualization. List of annotations and info about them: attachments, plot, supervisor, description.
5 Annotations

 Alerts visualization. List of alerts and info about them: supervisor, description and actions.
6 Alert details

 Prunes visualizations. List of prunes and info about them: supervisor, description and plot.
7 Prune details
 Treatments and treatment plan. List of treatments and treatment details showing info like: supervisor, ma-
chine, liters and security info.
8 Treatment details

It also shows the treatment plans info: Date, description, product list and quantities, and ID.
9 Treatment plan details.
