% gem install pg -- --with-pg_config=/usr/pgsql-9.2/bin/pg_config You need to customize your configuration parameters like so (see the `config/environments/example.rb` first): % $EDITOR config/environments/development.rbRun setup: % bundle install % bundle exec rake spec % bundle exec rake yardUtilities---------Assemble all your metadata and data as described in *Data Wrangling* into thestage directory `/var/geomdtk/current/stage`. The utilities will use `/var/geomdtk/current/workspace` as the output folder, akin to `/dor/workspace`.Caveats: to enable logging for the Rest client, use % RESTCLIENT_LOG=stdout bundle exec ...Preparing `stage`===============To assemble the workspace, populate the *geohydra.stage* directory with`druid` directories which contain the data as described in the Data Wranglingsection below.To generate the `geoOptions.json` files which contain inspections of the Shapefiles: % bin/geohydra build_stage_optionsTo ingest ArcGIS `*.shp.xml` files and transform into ISO 19139 files % bin/geohydra ingest_arcgis To package up the .shp files into .zip files: % bin/geohydra assemble_dataPreparing workspace with assembly=================================To load the `workspace` and generate metadata files from the `stage`, use: % bin/geohydra assemble If you're using a gazetteer, then post-process the MODS records with: % bin/geohydra assemble_placenamesTo project all Shapefiles into EPSG:4326 (WGS84), as needed: % bin/geohydra derive_wgs84 druid1... Accessioning============To upload the druid metadata to DOR: % bin/geohydra accession druid1 [druid2 druid3...] Upload workspace files to lyberservices-prod:/dor/assembly: % cd /var/geomdtk/current/workspace % rsync -av ./ lyberadmin@lyberservices-prod:/dor/assembly/ Use Argo to initiate the assemblyWF.To upload the druid packages to PostGIS, you will need `shp2pgsql` then use: % bin/geohydra loader_postgis druid1 [druid2 druid3...]Then, login to GeoServer and import the data layers from PostGIS % bin/geohydra sync_geoserver_metadataTo upload the druid packages to GeoServer use OpenGeo's *Import Data* feature. Or if you need an automated tool see `bin/loader.rb`.To upload the OpenGeoPortal Solr documents, use: % bin/geohydra solr_indexerData Wrangling==============Step 1: Preparing for stage---------------------------The file system structure will initially look like the following (see [Consulpage]( for a description) where the tempfiles for the shapefiles are all hard links to reduce space requirements: Thisis *pre-stage*: zv925hd6723/ temp/ geoOptions.json OGWELLS.dbf OGWELLS.prj OGWELLS.shp OGWELLS.shp.xml OGWELLS.shxThe `geoOptions.json` contain meta-metadata about the package, including thedruid, geometry type, and filename. These files can be generated using`bin/build_stage_options.rb` but it requires manual supervision. { "druid":"cg716wc7949", "geometryType":"Raster", "filename":"world_admin1.tif" }Step 2: Staged--------------Once staged, the data look like this: zv925hd6723/ content/ preview.jpg temp/ geoOptions.json OGWELLS-iso19110.xml OGWELLS-iso19139.xmlStep 3: Assembly----------------Then at the end of assembly processing -- see above prior to accessioning -- it willlook like in your workspace: zv925hd6723/ metadata/ contentMetadata.xml (generated later by accessioning scriptie) descMetadata.xml geoMetadata.xml content/ (optionally) preview.jpg some-other-file.ext (optionally) temp/ iso19139.xml ogpSolr.xml spatialSolr.xmlCredits=======Author: Darren Hardy , Digital Library Systems and Services, Stanford University Libraries
