Hi Jeff, Very timely email! There is another repository that has some similarities to RAMADDA: GeoNetwork. GeoNetwork also has a simple http repository for files which I would really like to replace with RAMADDA's scientific content management system and it seems a natural fit for RAMADDA to provide metadata fragments from its content types to fill out some of the metadata fields in GeoNetwork metadata records (we already can harvest metadata from THREDDS to fill out fragments of ISO metadata records). On the flip side, GeoNetwork has pretty good support for a lot of metadata standards (especially ISO and profiles) etc, good basis in Lucene search, some nice metadata catalog operations (harvesting protocols etc) and nice acceptance from a lot of organisations so there are benefits for RAMADDA if GeoNetwork was to handle the metadata side of RAMADDA. I've had quite a look at and evaluation of RAMADDA and am definitely interested in fostering direct, resourced collaboration on bringing the benefits of both RAMADDA and GeoNetwork together. I am a member of the GeoNetwork Project Steering Committee and would definitely like to discuss this further! Cheers, Simon ---- PS: Also fixed a nagging bug sometime ago with the RAMADDA THREDDS harvester (1.5a) a few months ago - but never got round to supplying it to you - can I email you the simple patch? ________________________________________ From: thredds-bounces@xxxxxxxxxxxxxxxx [thredds-bounces@xxxxxxxxxxxxxxxx] on behalf of Jeff McWhirter [jeff.mcwhirter@xxxxxxxxx] Sent: Monday, 24 June 2013 10:46 PM To: THREDDS Subject: [thredds] data repository survey Hi all, The Unidata folks recently presented a survey of data repositories: http://www.unidata.ucar.edu/committees/usercom/2013Apr/summary.html The intent was to identify and compare systems that are similar to RAMADDA (http://ramadda.org) and presumably the TDS. Some of the systems mentioned were new to me and the survey does not provide much detail on them. For all of you TDS users out there - Has anyone tried the above mentioned systems - e.g, ckan.org<http://ckan.org>, dataone, science base What other systems have you evaluated? (ESRI Geoportal, EuroGEOSS broker, ???) What kinds of features do they have that you have found useful? What features would you like to see in a data repository? For those of you who aren't familiar with RAMADDA below is a quick overview of some of its features. -Jeff RAMADDA is a data and information management framework that supports all kinds of digital "stuff". Some of the key features include: Extensible content type system Extensible metadata framework - define new metadata types via xml - e.g., DIF, THREDDS, etc Model-View framework: content encodings include various HTML views (mapping, calendar, timeline), JSON, Geo-RSS, ATOM-XML, DIF, CSV, THREDDS Catalog, ICAL, etc. Content management services - create, read, update, delete (CRUD) Fully featured HTML template facility User and role-based access control Comprehensive plugin framework Rich search - text, spatial, temporal and faceted metadata APIS - Publishing APIs, OAI-PMH, OpenSearch, import/export Integrated rich content wiki facility Virtual repository facility RAMADDA environment: 100% Java, Open-source (https://sourceforge.net/projects/ramadda/) Built on the standard Java servlet framework and runs under any servlet container - e.g., Tomcat, Glassfish or runs from the command line with Jetty Uses *any* JDBC compliant relational database - Derby, H2, Oracle, PostGRES, mySQL Web-based administration and configuration Integrated user model or external authentication via LDAP, etc Gridded data: ses the Java NetCDF stack spatial, temporal and faceted metadata extraction and search spatial and temporal subset service, time series extraction service OpenDAP Metadata browse and NCML generation NCO (NetCDF Operators) and CDO (Climate Data Operators) integration NCML-based data model modifications, grid aggregation IDV-based server side visualization Climate model data management and analysis package Point data: File reader framework - over 40 file formats to date spatial, temporal and faceted metadata extraction metadata and data browse, mapping and charting spatial, temporal and paramater value based subset aggregation point format conversions - to NetCDF, LAS, CSV, etc. gridding and product generation web service API Other data types and services: Structured information - bibliography, Blog, Glossary, FAQ, Notes, Photo album Science project ontology constructs -program, project, site, visit, campaign, dataset shapefiles, GPX, raw GPS, RiNEX, all radar file formats, FITS astronomy data email ingest and publishing service, SMS integration with Twilio Extensible structured lists - bookmarks, todo, status board, tasks, etc
