DESCRIPTION:G3W-SUITE is a modular\, client-server application (based on QG
 IS-Server) for managing and publishing interactive QGIS cartographic proje
 cts of various kinds in a totally independent\, simple and fast way.\nThe 
 suite is made up of two main components: G3W-ADMIN (developed through Pyth
 on\, using Django ) as the web administration interface and G3W-CLIENT as 
 the cartographic client.\, developed using a modular approach and is based
  on a “reactive programming” paradigm using Vue.Js\, Javascript framew
 ork and OpenLayer3.\nThis components communicate through a series of API R
 EST.\nThe application is compatible with QGIS 3.22 LTR and it is based on 
 strong integration with the QGIS API.\nIt is released on GitHub with Mozil
 la Public Licence 2.0\nMany graphic/functional aspects of the WebGis publi
 cation derive directly from QGIS projects as\, first of all\, the general 
 and OGC services capabilities.\nThe suite automatically inherits aspects r
 elated to the project (themes\, 1: N relations\, simple and atlas print la
 yout\, filter on legend based on map content\, layer display order and act
 ivation status ...) and related to individual layers (activation scale\, i
 nterrogability\, published attribute fields\, join attributes\, attribute 
 form\, editing widgets ...) .\nOf particular interest is the strong integr
 ation with the QGIS DataPlotly plugin.\nQGIS projects can be published as 
 WebGis services via direct upload (no plugins needed) on the Administratio
 n component.\nThe granular system of permissions and the subdivision into 
 roles of users (individuals or groups) allows the management of services t
 o be delegated to second and third level administrative users.\nIt is also
  possible to define consultation permissions on individual WebGis services
  and editing permissions on individual layers with different editing power
 s per user.\nFinally\, it is possible to define geographic and alphanumeri
 c constraints (both in consultation and in editing) differentiated by indi
 viduals or groups of users. Alphanumeric constraints can be based on SQL l
 anguage or QGIS expressions.\nIt is also possible to define for each layer
  aspects relating to the preparation of predefined searches\, caches and d
 ownloads in various formats.\nA particularly advanced function is related 
 to online editing and to the possibility of easily creating web cartograph
 ic management systems by defining the various aspects at the level of the 
 QGIS project.\nThis function (operating directly on the data through the Q
 GIS API) allows multi-user editing thanks to a feature-lock system.\nEditi
 ng works both at the geometric level (with intra- and inter-layer snap)\, 
 and at the attributes level (editing form and the widgets included) also c
 onnected by joins or 1:N relationships.\nThe call will allow to illustrate
  the innovations of the current and future versions.\nThese include the im
 plementation of editing functions\, user-based filters linked to the visib
 ility of layers and attributes\, the possibility of using QGIS projects ba
 sed on embedded base projects and the integration of the vectorial and ras
 ter Temporal Controller of QGIS.\nOnline geographic analysis possible than
 ks to the integration of Processing algorithms through dedicated APIs.
