# Data transaction of the Token Rating oracle
Once a day, the Token Rating (opens new window) oracle sends to the blockchain a data transaction with ratings and rates of tokens.
A data transaction contains the information about tokens, that have been rated in the past 24 hours.
A single transaction contains the information about no more than 25 tokens — if there are more rated tokens, then several transactions will be sent.
An example of a data array of such a transaction:
"data": [
{
"key": "assetRating_BsL9uRX4bucKcSY7rfUPhqKjXiWomUQTGFGhodNySACb_1"
"type": "integer",
"value": 43,
},
{
"type": "integer",
"value": 28343,
"key": "assetWeight_BsL9uRX4bucKcSY7rfUPhqKjXiWomUQTGFGhodNySACb"
},
{
"type": "integer",
"value": 12,
"key": "assetVotes_BsL9uRX4bucKcSY7rfUPhqKjXiWomUQTGFGhodNySACb"
},
{
"key": "scoreBoard_BsL9uRX4bucKcSY7rfUPhqKjXiWomUQTGFGhodNySACb"
"type": "string",
"value": "{\"1\":{\"votes\":0,\"tokens\":0},\"2\":{\"votes\":1,\"tokens\":322},\"3\":{\"votes\":0,\"tokens\":0},\"4\":{\"votes\":0,\"tokens\":0},\"5\":{\"votes\":1,\"tokens\":1120}}",
},
...
{
"type": "integer",
"value": 45,
"key": "tickerRating_1"
},
{
"type": "integer",
"value": 10000,
"key": "tickerWeight"
},
{
"type": "integer",
"value": 11,
"key": "tickerVotes"
}
]
The key field is formed by concatenating (opens new window) a string that describes the parameter and a string with the ID of a token.
| Key | Type | Description |
|---|---|---|
| assetRating_assetId_1 | integer | Rating of the token (multiplied by 10) |
| assetWeight_assetId | integer | WCT weight of the token |
| assetVotes_assetId | integer | Votes sum of the token |
| scoreBoard_assetId | string | The value the field contains an escaped string (opens new window) with rates. |
| tickerRating_1 | integer | Service parameter, which contains the value of the Rating (multiplied by 10), which must be at the token in order for the ticker to be set by its issuer |
| tickerWeight | integer | Service parameter, which contains the value of the WCT weight, which must be at the token in order for the ticker to be set by its issuer |
| tickerVotes | integer | Service parameter, which contains the value of the Votes sum, which must be at the token in order for the ticker to be set by its issuer |
# An example escaped string with rates
Let's say we have an escaped string with rates:
"{\"1\":{\"votes\":0,\"tokens\":0},\"2\":{\"votes\":0,\"tokens\":0},\"3\":{\"votes\":3,\"tokens\":545},\"4\":{\"votes\":0,\"tokens\":0},\"5\":{\"votes\":2,\"tokens\":3827}}"
Let's unescape that string:
{
"1": {
"votes": 0,
"tokens": 0
},
"2": {
"votes": 0,
"tokens": 0
},
"3": {
"votes": 3,
"tokens": 545
},
"4": {
"votes": 0,
"tokens": 0
},
"5": {
"votes": 2,
"tokens": 3827
}
}
It follows from the string that no one rated the token with one, two or four stars.
Three users rated the token with three stars. The sum of the weights Wn of those rates is 545.
Two users rated the token with five stars. The sum of the weights Wn of those rates is 3827.
