Best Practices

This page outlines the best-practices for metadata and data, used in the EMO-BON project.

1. Metadata¶

• RO-Crate Metadata¶

  • Use schema.org terms when available

  • Use established ontologies (SOSA, DublinCore)

  • Define custom terms in EMO-BON namespace

  • Provide human-readable labels

• Dates and Times¶

  Use ISO 8601 format:

  • Date: YYYY-MM-DD

  • DateTime: YYYY-MM-DDTHH:MM:SSZ

  • Time period: YYYY-MM-DD/YYYY-MM-DD

• Geographic Coordinates¶

  • Latitude/Longitude in decimal degrees

  • Use WGS84 coordinate reference system

  • Include precision information

2. Identifiers¶

• Observatory IDs¶

  Format: lowercase with hyphens
  Examples:

  • bpns

  • hcmr-1

  • roskogo

  Used In:

  • Repository names: observatory-bpns-crate

  • URIs: https://data.emobon.embrc.eu/observatory-bpns-crate

• Sample IDs¶

  Format: EMOBON_{OBSERVATORY}_{TYPE}_{NUMBER} Examples:

  • EMOBON_BPNS_Wa_001

  • EMOBON_HCMR-1_So_042

  Components:

  • EMOBON: Project prefix

  • {OBSERVATORY}: Observatory ID in uppercase

  • {TYPE}: Sample type (Wa=water, So=sediment)

  • {NUMBER}: Sequential number

• Sampling Event IDs¶

  Format: {OBSERVATORY}_{TYPE}_{YYMMDD}
  Examples:

  • BPNS_Wa_221027

  • HCMR-1_So_230615
