ZJSON Encoding: Mapping of Metadata Key Types to Object Names
Every Metadata key is mapped to an object name where its value is encoded.
| Type | JSON Object Name | Remark |
| Credential | "s" | A string with the decrypted credential. |
| EString | "s" | A possibly empty string. |
| Identifier | "s" | A string containing a zettel identifier. |
| IdentifierSet | "y" | An array of strings containing zettel identifier. |
| Number | "s" | A string containing a numeric value. |
| String | "s" | A non-empty string. |
| TagSet | "y" | An array of string containing zettel tags. |
| Timestamp | "s" | A string containing a timestamp in the format YYYYMMDDHHmmSS. |
| URL | "s" | A string containing an URL. |
| Word | "s" | A string containing a word (no space characters) |
| WordSet | "y" | An array of strings containing words. |
| Zettelmarkup | "i" | A sequence of inline-structured elements. |
Please note, that metadata is weakly typed. Every metadata key expects a certain type. But the user is free to enter something different. For example, even if the metadata type is number
, its value could still be abc
. However, the mapping itself is always valid.
