Model Driven Metadata Editor (MDME): web application for geospatial metadata editing

A web based (Node/Vue.js) application to populate YAML/JSON oriented metadata records. The editor supports multiple metadata models (and models can be extended), currently supported are:

• MCF
• OGC API - Records
• Data Package

The app is currently in BETA, improvement suggestions very welcomed.

Deployment of latest version can be found at GitHub.io.

Capabilities

• Open local metadata (MCF)
• Import metadata from:
  • DOI (extract DOI metadata as DataCite)
  • WMS (extract metadata from Capabilities)
  • iso19139 (via metadata conversion service provided by pygeoapi.io
• Export metadata (via metadata conversion service)
  • iso19139
  • OGCAPI-Records
  • Spatio Temporal Asset Catalog (STAC)
  • DCAT
• edit metadata
• save metadata

Note that the application runs client side only. No content is send to a server. Although the client can easily be extended to store the output in a Git repository or a catalogue system, like pygeoapi, pycsw, Geonetwork opensource or CKAN.

Exceptions are import and export metadata, which use a metadata transformation service provided by demo.pygeoapi.io.

About MCF

Metadata is saved in the Metadata Control File (MCF) format. The format is encoded as YAML, which is a readable file format and optimal for content versioning in a Git repository. When alternate formats are needed (iso19115, DCAT, STAC), you can export to these formats using a transformation service provided by the pygeoapi demo server based on pygeometa.

Installation

Requires:

• Node.js
• Yarn

git clone https://github.com/osgeo/mdme.git
yarn install
yarn serve

Visit localhost:8000.

Configuration

Configure vocab in app.vue on which schema to use, MCF, OGC API - Records or Data Package.

Models are defined in models/{model}/model.json. Very welcome to adjust the existing schema's or add a new one.

Vuetify JSON Schema Form

The library vjsf uses a json-schema definition to render a form. Some special fields ('x-display: 'hidden') are added to the schema file to enrich vizualisation.

MCF introduces contacts and distributions as key-value pairs. This pattern is not supported by vsjf. For this reason contacts and distributions are converted to array at loading time and back to object when saving.
