Vocabulary for describing an AppData object. An AppData is the value of an appData attribute of a TemplateContext. An AppData and its sub-objects represent the (i) app-related attributes of the person entity and (ii) the metadata and parameters needed for the app itself. Part of the Persona Data Model 2.0

Classes

AppData

Description of an app

  • 1..1 description
  • 1..1 version
  • 1..1 eventHandlerURL
  • 1..1 adminURL
  • 1..1 serviceType
  • 1..1 serviceURL
  • 0..1 params
  • 0..N hbxFunctionsEnabled
  • 0..N sites
  • 0..N entityParam

AppParams

An AppParams instance is the value of an AppData's params attribute. It is a set of attributes and values used to initialize the app. Note: these attribute/values are combined with those derived from the AppData's entityParam.

AppData Attributes

adminURL

The URL of a admin page to load into PDS portal.

  • domain: AppData
  • value: xsd:anyURI

appId

Uniquely identifies the app within the "developerId" namespace. In other words the combination of the devID and the appId is globally unique. When using Kynetx KNS this is the ruleID with special constraint that this ruleID is globally unique.

  • domain: AppData
  • value: string

description

A human readable description of the app. Note: If appServer == http(s)://init.kobj.net, then the KNS "describe" API can be used by a context provider implementation to provide this attribute value.

  • domain: AppData
  • value: string

entityParam

The name of an attribute (e.g. p:postal-code) of a Person within a context associated with this App-data object. The value of this named attribute of the person is used as a parameter to the app-card's app.

  • domain: AppData
  • value: URI

eventHandlerURL

The URL of JS that provides specific handlers for certain events in a context’s lifecycle including: onImport, onDelete, onEnable, onDisable, onExport

  • domain: AppData
  • value: URI

hbxFunctionsEnabled

The list of HBX functions that the JS functions associated with this app-data are allowed to call.

  • domain: AppData
  • value: string one of: {"delExAttrbutes" , "getExAttributes" , "getSuggestions" , "setExAttributes"}

params

A set of attributes used to initialize the app.

  • domain: AppData
  • value: AppParams

serviceURL

The URL of the JS to fetch and execute.

  • domain: AppData
  • value: URI

serviceType

If value is "kynetx" then the browser extension that will inject the Javascript for this app-card should construct a Kynetx-compatible <script> block and call an initialization URL based on the value of the appService attribute.

  • domain: AppData
  • value: string whose value is one of ("kynetx", "higgins").

sites

This is not a list of specific URIs, it is a list of strings to match in the domain name part of a URI. So urn:google would fire on maps.google.com, www.google.com, www.googleismyfavoritesite.com. For Kynetx-powered cards (i.e. if appServer = http[s]://init.kobj.net"), the values of this attribute should be dynamically fetched using the 'dispatch' method at URL: [1]<appId>.

  • domain: AppData
  • value: string

version

A human readable version of the app. Note: If appServer == http(s)://init.kobj.net, then the Kynetx KNS "describe" API can be used by a context Provider implementation to provide this attribute value.

  • domain: AppData
  • value: string

Related Person attributes

As we've mentioned, an AppData instance is the value of an appData attribute of a TemplateContext. For example we might have AppData1 as the value of appData on TemplateContext TC1. A context, C1, might be based on TC1. Within C1 usually exists a Person node. The following attribute are optional attributes of this Person node.

enabledSites

The URLs of sites that the user has enabled the app to run on. Note that this augments the appSites value provided by the app developer which indicates the set of sites the app was designed to run on.

  • value: boolean

disabledSites

The URLs of sites that the user has disabled the app from running on.

  • value: xsd:anyURI

appEnabled

If true run this app

  • value: xsd:anyURI

Example AppData

Example of an AppData context:

App-data-examplev8.png

Shown above is an example TemplateContext with an associated AppData object. Also within this context is an entity, 'me'.

Notes:

  1. Of particular interest is the app-card:params attribute whose value is the AppParams_1 object. The AppParams_1 in turn has two app initialization attributes, randomAttribute1 and 2.
  2. Since "appEnabled" = true attribute/value is not present on 'me' its value is assumed to be false and the card is thus disabled at present.

Processing Model

Invoking Javascript

The Higgins browser extension is responsible for invoking the app/Javascript for all app-data contexts. This is done three ways. If appJS is not nil, then its value IS the app to invoke. If the appJS is nil, then the appServiceType indicates whether a Kynetx-style KNS invocation should be done or an (as yet undefined) Azigo-style invocation from some Azigo-hosted web service should be done. In the above example the appServiceType = kynetx so a KNS invocation will be done.

App/rule Id parameter

In the non-appJS (i.e. kynetx and/or azigo cases) the appId is required to specify which app (Javascript program) should be run. In the above example the appId (called a rule id by KNS) is "1024".

Before the Javascript is invoked on a given Web page HBX must determine for each AppDataContext if the current page is one that matches one or more card's site list.

Gather parameters to the Javascript

The browser extension and supporting code must implement the following algorithm to gather all necessary parameters to the Javascript function:

  • Get the value of all attributes of the entity of the "appParams" attribute of the context object (ignoring rdfs:comment, rdf:label attributes, rdf:type, etc.).
  • Get the value of all attributes of the main p:Person entity that are named in the context object's entityParam attribute value(s).

Making parameters/values available to the app (Javascript)

How parameters are inserted varies by service type. Here is how it is done for a "kynetx" serviceType:

var KOBJ_config ={
   "rids"  : ["1024","xyz123"],
   "1024:dataset" : "aaawa",
   "1024:dataset" : "ebates",
   "1024:favorite-song" : "Billy Joel: The Piano Man",
};

This tells kynetx to run rules 1024 and xyz123, and for rule 1024, use dataset=aaawa and dataset=ebates. Note that each appParam value is namespaced by the appId (aka rule id, or rid) to which it is associated.
