HIERARCHICAL METADATA STRUCTURE

The EHI metadata is organised at three hierarchical levels: sampling event, animal specimen and sample. The three levels are inter-related through unique identifiers.

FIELD METADATA SHEETS

There are two optional field metadata sheets that enable collecting all the required metadata. The first sheet contains information of the sampling events (A), while the second incorporates information of animal specimens (B1) and samples (B2).

ELECTRONIC METADATA DOCUMENT

The metadata information need to be sent electronically to the EHI management team using the standardised metadata sheets, which contain three tabs with information about sampling events (A), animal specimens (B1) and samples (B2).

Hierachical metadata

The EHI metadata is organised in three hierarchical levels 

METADATA A
Sampling event metadata 

METADATA B1
Animal specimen metadata 

Metadata B2
Sample
metadata

Unique identifiers

The hierarchical metadata levels need to be related through unique identifiers. Sampling event (A) and Animal Specimen (B1) identifiers are specified by the field samplers, while the sample identifiers (B2) are already set in the sample collection tubes.

Sampling event identifiers

Each sampling event (unique location and date) must receive a different identifier specified by the sampler*. This identifier enables relating sampled animals to their corresponding sampling events.

Animal specimen identifiers

Each sample animal specimen must receive a different identifier  specified by the sampler*. This identifier enables relating each sample to its corresponding animal specimens' metadata.

Sample
identifiers

Each sample storage tube contains a 3-letter and 2-number code (e.g. ABC01) that needs to be related to an animal specimen identifier.

* user-defined identifiers are replaced by standard codes when incorporating to the central EHI database

Field metadata sheets

We provide optional sheets to collect all the necessary information in the field. 

METADATA SHEET A
Sampling event metadata

A vertical A4-size document designed to collect sampling event information of 3 samplign events

METADATA SHEET B

A horizontal A4-size document designed to collect specimen information of three animals and up to six samples per sampled specimen.

Electronic metadata document

All metadata needs to be incorporated in a standard electronic document and forwarded by email to the EHI management team
