Represents a piece of data in the system, such as a file or a text. Fields match the Python cognee data table schema for cross-SDK compatibility.

Fields

id: Uuid

Unique identifier for this data record (UUID v5, deterministic from content hash)

name: String

Display name derived from the source (filename, URL, or text_<md5>.txt for inline text)

raw_data_location: String

file:// URI pointing to the stored raw content in the file storage backend

original_data_location: String

Original source location before any processing (file path, URL, or same as raw_data_location for inline text)

extension: String

File extension of the stored content (e.g. “txt”, “pdf”, “html”)

mime_type: String

MIME type of the stored content (e.g. “text/plain”, “application/pdf”)

content_hash: String

MD5 hex digest of the raw content bytes (content-only, no owner mixing)

owner_id: Uuid

ID of the user or agent that owns this data record

created_at: DateTime<Utc>

Timestamp when this record was first created

updated_at: Option<DateTime<Utc>>

Timestamp of the last update to this record, if any

label: Option<String>

Human-readable label for the data item (from DataItem wrapper or user-provided)

original_extension: Option<String>

Original file extension before any conversion

original_mime_type: Option<String>

Original MIME type before any conversion

loader_engine: Option<String>

Python loader engine name (e.g. “text_loader”, “pypdf_loader”)

raw_content_hash: Option<String>

MD5 hash of the extracted-text file stored by the loader at ADD time (Python parity, ingest_data.py:195). Equals content_hash only when the extracted text is byte-identical to the raw input (plain text); for inputs the loader transforms (PDF, CSV, HTML, image, audio) the two hashes differ.

tenant_id: Option<Uuid>

Tenant/organisation ID for multi-tenant isolation

external_metadata: Option<String>

Arbitrary JSON metadata blob

node_set: Option<String>

JSON list of node IDs associated with this data item

pipeline_status: Option<String>

Pipeline processing status

token_count: i64

Token count of the data (-1 = not yet computed)

data_size: i64

Size of the data in bytes (-1 = not yet computed)

last_accessed: Option<DateTime<Utc>>

Last access timestamp

importance_weight: Option<f64>

Importance weight for ranking (0.0 to 1.0). Influences relevance scoring.

Implementations

impl Data

pub fn builder( id: Uuid, name: impl Into<String>, raw_data_location: impl Into<String>, original_data_location: impl Into<String>, extension: impl Into<String>, mime_type: impl Into<String>, content_hash: impl Into<String>, owner_id: Uuid, ) -> DataBuilder

Start building a new Data record with the required fields. All optional fields default to None; data_size defaults to -1.

Trait Implementations

impl Clone for Data

fn clone(&self) -> Data

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Data

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Data

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Data

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
