Classification labels (e.g., epa, echa).
Structural type of a document section node.
Identifier of the harvester that sourced a document.
A column in a brick table. Carries a vocabulary annotation that resolves the column to a stable concept URI: a column whose annotation matches a known controlled-vocabulary convention resolves to a well-known chemical or biological term (e.g., CAS Registry Number, SMILES, InChIKey), and a column with no matching convention resolves to a term minted under the owning brick's instance namespace, scoped to that brick, table, and column.
Scientific domain (e.g., Toxicology, Genomics).
Provenance links from this section to the tool calls that produced its value.
The root-level sections of this flow's document tree.
A persisted record of a tool invocation, capturing the input arguments, output, and the conversation it occurred in. Identified by (conversation_id, tool_call_id). Citations in flow documents resolve to these.
A multi-turn question-and-answer session with the platform's agent.
Guidance on how to use this collection for retrieval.
A single table within a brick. Contains typed, described columns with optional mappings to external ontology terms.
The tool invocation that produced this section's value.
Number of sections currently being worked on.
Identifier of a specific tool invocation within a conversation.
Structured object with named child fields.
Whether the tool invocation resulted in an error.
A provenance link from a document section to the tool invocation that produced or supported its value.
JSON-serialized input arguments to the tool.
Dot-delimited path to a node in a flow document tree.
JSON Schema defining the tool's accepted input.
Stable URI for this column's concept. A column whose convention has an established public-ontology term resolves to that external URI (e.g., cheminf:CHEMINF_000446 for cas_number); a convention without one resolves to a ToxIndex-minted vocabulary term; a column with no convention resolves to a term minted under the owning brick's instance namespace, scoped to that brick, table, and column.
Available output formats (e.g., html, pdf, json).
A curated group of documents sharing a common source or topic. Collections form a shallow hierarchy with one level of nesting.
The workflow this flow is an instance of.
A computational capability available on the platform, such as a QSAR model, a descriptor calculator, or a metabolite predictor. Tools accept structured input (typically a SMILES string) and return structured output.
A curated reference dataset, such as a regulatory list, a chemical property table, or a biological endpoint dataset. Each brick contains one or more typed tables with column-level vocabulary annotations.
Controlled-vocabulary annotation a brick column carries (e.g., CAS, SMILES, InChIKey). Backed by a stable convention that determines how vocab_uri resolves.
A repeatable structured process that produces a document, such as a regulatory assessment or a technical evaluation report. Workflows define a schema that guides structured content generation with cited evidence.
Column names forming the table's primary key.
Canonical source URL for a dataset or tool.
Total number of sections in the document.
User-facing domain ontology for ToxIndex. Defines the concepts that customers and integrations consume: curated reference data, document corpora, computational tools, structured workflows, and their provenance.
Parent collection (one level of nesting).
An instance of a workflow execution. A structured, schema-conformant document being filled out (or completed) with provenance citations linking each section back to the tool call that produced it.
A node in a flow document tree. Sections are the structural building block: each has an identity, a kind (object, list, scalar, enum), a status, and optional citations linking its value back to tool calls. Workflow schemas define what sections exist; the ontology defines the shape they all share.
An indexed document in the platform's regulatory and scientific corpus. Sourced by a crawler, optionally grouped into collections.
