Record Syntax
JSON Format
A single record may be encoded as a JSON object:
| Property | Value |
|---|---|
| <field name / label> | field type appropriate value / null |
"expressions" |
JSON object mapping field name/label to expression |
"file" |
binary object (if database has file enabled) |
"tags" |
JSON array of string(s) (if database has tag enabled) |
The "expressions" property allows field values to be specified by expression, rather than explicit value. Between the base object and "expressions" object, field may only have a single value provided, or an error will be thrown.
Multiple records may be encoded as a JSON array of JSON objects in this format.
DSV Format
Record data may be provided in a delimiter separated values format. In this case the record data itself is contained in a binary object.
| Property | Value |
|---|---|
"type" |
"dsv", "csv", or "tsv" |
"file" |
binary object |
"delimiter" |
string (required for "dsv") |
"quote" |
string (optional) |
The "csv" and "tsv" types specify default delimiters of comma (,) and tab (\t), respectively.
Example
{
"records": {
"type": "dsv",
"file" : "<object ID>",
"delimit": ";"
}
}
The format of the separated values file is largely based on the RFC 4180 standard. The specific requirements are:
- lines must end with
LF(\n) orCRLF(\r\n) - line breaks cannot be used in values
- the default quote character is
"(double quotes) - any field may be quoted by the quote character
- any field containing the delimiter must be quoted
- a quote character in a quoted value must be represented by two quote characters
- the first row must contain the names of each field
- blank lines with no data are ignored
