Each field has a label, an ID, a section and a field type. The fields are defined for the whole database. Therefore they can be used in different Database Schemes.

The Field ID may only contain letters, the characters +-_()[] and digits. The label is usually displayed instead of the Field ID, it can contain any characters.

Different field types are available

• Free text
• Predefined values
• Date
• Numbers
• Boolean (yes/no)

Text fields can have predefined values. In this case, at least one predefined value must be given. If New values addable is checked, the user can enter free text in addition to the predefined values.

Content of new fields that are created by the user is never submitted to cgMLST.org or EBI ENA.
