Contributions to GeoNetwork trunk at version 2.2 (01/08) from the BlueNetMEST sandbox
Contribution	Description
ISO19139 schema parsing	Re-wrote the schema parser to accommodate much more complex schemas – in particular, the new ISO19139 implementation of ISO19115 Also tested on other complex schemas including sensorML
Editor enhancements to support ISO19139	Changes required as the old editor was based on ISO19115 DIS
Schematron validation – checking conditions and content and editor tags	Validation against XML schemas did not allow checking of conditions (eg. If hierarchyLevel dataset then must have geographic extent etc) and content (eg. Organisation name must be present and not blank) – added framework to support schematron XSLTs as part of the validation process and visual flagging of elements involved in schematron errors in the editor.
ISO Profile support	Need to include profiles of ISO19115 without duplicating existing implementation for each profile – eg. Presentation, help information, titles/labels etc
Bug fixes

Contributions to GeoNetwork trunk at version 2.4 (04/09) from the BlueNetMEST sandbox
Contribution	Description
Editor enhancements – Ajax controls, XML schema validation errors	Operating the editor controls (eg. +, x, ^, v) in the editor (prior to 2.4) submitted the entire form forcing a save of the metadata record – the editor controls in 2.4 now use Ajax techniques and do not submit the entire form for saving – in addition the document is stored in the user session until saved.
Massive Operations/Operations on selected sets of metadata	New Owner, Categories, Privileges – these operations were written to use the SelectionManager
Download of file data attached to metadata now includes license/constraint info plus file(s) in a zip archive a zip archive	Automatically generated license annex (uses Commons license in MCP or constraint info in base ISO19115 standard), metadata snapshot (in a MEF) and selected files are placed in a zip archive for download
User self-registration system	Self-explanatory
Finer grained permissions – split ownership and editing	Ownership rights added: only owners can delete, change privileges and categories of a metadata record. Editing privilege was added (actually restored - it had been removed in 2.2) – owners can assign it to anyone in the groups they belong to.
Shibboleth authentication	Added capability for users to be authenticated against shibboleth infrastructure (eg. AAF)
Switch to saxon XSLT engine, XSLT caching	XSLT caching removes the need to recompile stylesheets each time they are used. Saxon XSLT engine is faster and supports a wider range of XSLT 2.0 features than Xalan.

Composed Metadata Records with THREDDS and WFS harvester to construct composed metadata records	http://trac.osgeo.org/geonetwork/wiki/ComposedMetadataRecords
Mime Type calculation and indexing for online resources attached to a metadata record	http://trac.osgeo.org/geonetwork/wiki/MimeTypeCalculationIndexing
Search on temporal extent	http://trac.osgeo.org/geonetwork/wiki/TemporalExtentSearch
Performance Enhancements to search	http://trac.osgeo.org/geonetwork/wiki/PerformanceEnhancements2
Harvesters can do validation of harvested content and run import XSLTs on harvested content	Two new options that any harvester can use have been added to support these features – they are currently used by Z3950 harvester and Local file system harvesters
Bug fixes

BlueNetMEST sandbox features not yet in trunk – 1.4 June 2010
Feature	Description	Reason
ANZLIC, MCP and ADO profiles of ISO19115	All information for national profiles	National profiles are not features that should exist in the trunk – ideally a plug in architecture should be present, or at least profiles should be provided as installer packs
Z3950 client (remote search tab)	An advanced search page that lets users specify terms and servers to be searched using Z3950	Unified local and remote search interface not yet ready
Spatial search in user interface and CSW	Use the spatial index in shapefile or PostGIS for search interface	For 2.7 or later
Tab-based page with metadata viewer/editor in separate window	Self-explanatory	Difficult to promote one communities user interface over another – this one has the advantage that search results are not disturbed by editing/viewing metadata records and supports editing/viewing more than one record at a time by design, map viewer has plenty of room in its own tab, remote search (and other tabs – see 'professional' search below) are easily added.
Advanced Search enhancements and fixes	Reset operation resets search defaults on the server, not just the fields in the form, many rarely used options are hidden by default thus simplifying the form, additional restrictions such as search on groups and records owned by the searcher have been added	Difficult to promote one communities user interface over another.
Professional search	Exposes the lucene query string to users. Allows saving and appending of lucene queries from browser session cookie – full power of Lucene search can be used eg. NOT, AND, OR by directly manipulating Lucene query strings	Focus in GeoNetwork appears to be on simplifying search, not providing more sophisticated features. Need for this feature is not understood by the community yet.
Simple metadata form	Metadata entry may discourage potential contributors – a simple form should be provided for contributors to provide a basic metadata description. This metadata can then be built on by metadata experts.	No clearly defined requirement for this feature exists in the GeoNetwork community.
MEF files exported and imported through GAST can include ownership/groupOwner	Default is to ignore this info.	Not committed as yet.
Other minor fixes and enhancements	Self-explanatory	These accumulate over time between trunk releases – when a trunk release is planned and new features from the BlueNetMEST are proposed, the appropriate minor fixes and enhancements are committed with the new features.
