| | 11 | == Overview == |
| | 12 | |
| | 13 | |
| | 14 | This proposal aims to move current GUI for search, view and editing to a new layout based on the work made in the [https://geonetwork.svn.sourceforge.net/svnroot/geonetwork/sandbox/guiwidgets/web-client/ widgets sandbox]. The main application is composed of one page which allows user to search, view and edit metadata records. The administration remains as it was. |

| | 40 | ---- |
| | 41 | |
| | 42 | == Motivations == |
| | 43 | |
| | 44 | The idea was to provide a sample client application which could be easily modified and customized for your needs. It depends on simple JS components. The view and edit mode still depends on GeoNetwork XSLTs rendering. |
| | 45 | |
| | 46 | == Proposal == |
| | 47 | |
| | 48 | A new maven module nammed "web-client" has been created for the client application. This module is only composed of JS and html page. YUI pluggin is used for compression (all in one file for the application + ext.js). The number of JS dependencies has been reduced to the minimum focusing on using : |
| | 49 | * !OpenLayers |
| | 50 | * Ext.js + some Ext.ux |
| | 51 | * !GeoExt.js + one !GeoExt.ux |
| | 52 | The overall size of JS decrease and the number of request for the page load also decrease which results on faster page initialization. |
| | 53 | |
| | 54 | |
| | 55 | The 2 GUI could coexist for some times event if it's probably better to clean the code base. Hook needs to be added to : |
| | 56 | * the admin create metadata action |
| | 57 | * the admin import results page |
| | 58 | |
| | 59 | New services has been created in order to make the old and new GUI work. |
| | 60 | XSLTs for view and edit mode has been refactored a bit and grouped in a metadata folder. |
| | 61 | Hardcoded CSS styles have been removed. |
| | 62 | |
| | 63 | |
| | 64 | === New feature : === |
| | 65 | |
| | 66 | * search form : |
| | 67 | * autocompletion (using !OpenSearch suggestion) |
| | 68 | * organisation search field |
| | 69 | * scale denominator search field |
| | 70 | * spatial representation type search field |
| | 71 | * validation status search field |
| | 72 | * search results : |
| | 73 | * Thumbnail view |
| | 74 | * Bbox highlighting |
| | 75 | * Zoom to bbox |
| | 76 | * Display organisation logo |
| | 77 | * validation status information |
| | 78 | * select "all in page" |
| | 79 | * summary by keyword to refine the current search |
| | 80 | * Metadata view : |
| | 81 | * a simple view mode by default |
| | 82 | * Editor : |
| | 83 | * suggestion panel |
| | 84 | * Interactive map |
| | 85 | * Search for WMS from the add WMS panel |
| | 86 | * Layer opacity slider in layer tree |
| | 87 | |
| | 88 | For the search results, access to all actions are available using a contextual menu (right click) or using the "Actions" menu which is displayed next to the title. |
| | 89 | |
| | 90 | === Missing feature : === |
| | 91 | |
| | 92 | * search form |
| | 93 | * distributed search form (Z3950RepositoryStore.js already provides access to the list of nodes) |
| | 94 | * INSPIRE search fields |
| | 95 | * search results (Template.js) |
| | 96 | * remote search when harvested |
| | 97 | * bbox, date |
| | 98 | * i18n : Update/Create language file from existing element in strings.xml. Add missing one (see lang folder). |
| | 99 | * Interactive map |
| | 100 | * WMSTime button to be restored |
| | 101 | |
| | 102 | |
| | 103 | === Backwards Compatibility Issues === |
| | 104 | None that I can see |
| | 105 | |
| | 106 | === New libraries added === |
| | 107 | New libraries : some ux for Ext.js (Rating). |
| | 108 | Libraries removed (for the client) : Scripaculos, Prototoype |
| | 109 | |
| | 110 | == Risks & improvements == |
| | 111 | |
| | 112 | Add missing features. |
| | 113 | |
| | 114 | Future improvements: Provide JSON response (from Jeeves services) to reduce the XML parsing on the client side. |
| | 115 | |
| | 116 | == Participants == |
| | 117 | |
| | 118 | * François Prunayre |
| | 119 | * Part of the JS libs comes from the geocat.ch work. |
