    3 The [http://ndg.nerc.ac.uk/discovery/ NDG discovery portal] provides a web portal accessible by standards compliant browsers that allows a user to freely discover datasets held by data providers who have offered up appropriately formatted discovery metadata for harvest by the discovery portal backend. Where NDG compliant data providers hold datasets, the portal will provide information about NDG services available for those services, and provide links to instantiate these services.

    15 1.      Revised Database Package (April 2006) (This database package also part of data provider package for storing all A,B and D docs). – needed? 
    16 2.      Revised Web Service Interface Package (April 2006). To support geographical queries and xqueries and respect NDG security. – will this be April? 
    17 3.      Revised GUI (May 2006). Improved geographical information and flag secure datasets, advanced search services for simulation data. – need some Numsim first 
    18 4.      Redeployed discovery service using new tools, and supporting the zserver (June 2006). – zserver support by March 31st for NMG). OAI automation required by then. 
    19 5.      NDG Alpha (Jul 2006, nothing beyond the above). 
    20 6.      Transition discovery archive to ISO19115 (September 2006).

    22 8.      NDG Final.  All scripts automated. 
     18Internal Milestones 
     19 * [wiki: T01zserver1] - internal NDG support for zserver harvesting to supplant old NERC metadata gateway. 
     20 * [wiki: T01DatabasePackage-prealpha] - to support all A, B and D documents. 
     21 * [wiki: T01WebServicePackage-prealpha] - to support geographical queries, and xqueries and respect NDG security 
     22 * [wiki: T01Gui-prealpha] - improve geographical information, flag secure dataset, support simulation data. (Requires NumSim) 
     23 * [wiki: T01zserver-2-prebeta] - support zserver queries on OAI databse 
     24 * [wiki: T01_ISO19115-prebeta] - support a "MetOcean" profile of ISO19115 as well as GCMD DIF
