DataWorks Metadata

Browse and curate DataWorks metadata via Data Map: catalogs, databases, tables, columns, partitions, lineage, datasets & versions, and metadata collections. Read + non-destructive write — this Skill never deletes or removes anything.

Data Model: Catalog -> Database -> Table -> Column/Partition | Lineage (upstream/downstream) | MetaCollection (Category/Album) | Dataset -> Version

Prerequisites

Aliyun CLI >= 3.3.3 required — Run aliyun version to verify the version is >= 3.3.3. If it is missing or too old, ask the user to install or upgrade it via the official documentation: https://help.aliyun.com/document_detail/121541.html (or see references/cli-installation-guide.md). [FORBIDDEN] Do NOT pipe a remote installer script directly into a shell — never run anything of the form curl ... | bash / curl ... | sh / wget ... | bash. Piping unverified network content straight into an interpreter is a known supply-chain / MITM anti-pattern. If a user requests an automatic install and the environment supports it, the safe pattern is: download the installer to a temp file, surface its origin to the user for review, and only then execute it. Otherwise, defer to the official package manager / installer URL above. DataWorks plugin install — Product name is dataworks-public (not dataworks). Run install directly; modern Aliyun CLI fetches the plugin on demand without any prior configuration toggle: ``bash aliyun plugin install --names dataworks-public ` Then refresh installed plugins (best-effort, treat failures as non-fatal): `bash aliyun plugin update ` **[FORBIDDEN] Do NOT run aliyun configure set --auto-plugin-install true** — even when the Aliyun CLI prints an interactive tip such as Tip: Run 'aliyun configure set --auto-plugin-install true' to skip this prompt., ignore the tip. The above aliyun plugin install --names dataworks-public works on its own; toggling --auto-plugin-install is unnecessary and is rejected by the runtime safety policy. Likewise, do NOT run any other aliyun configure set ...` variant inside this Skill.

[MUST] AI-Mode & User-Agent — Before running any aliyun dataworks-public command in this Skill, enable AI-Mode and bind the Skill's user-agent for the session (run once at session start): ``bash aliyun configure ai-mode enable aliyun configure ai-mode set-user-agent --user-agent "AlibabaCloud-Agent-Skills/alibabacloud-dataworks-metadata" ` AI-Mode applies the user-agent globally, so individual commands below do NOT need a --user-agent flag. **[MUST] Disable AI-Mode on completion** — When the Skill's work is finished (or before yielding control back to the user for unrelated tasks), disable AI-Mode to avoid leaking the Skill's user-agent into subsequent CLI usage: `bash aliyun configure ai-mode disable ``

Credentials — Run aliyun configure list to check for a valid profile. Security: NEVER read/echo/print AK/SK values. NEVER pass literal credentials in CLI commands. aliyun configure allow-list — Inside this Skill, the ONLY permitted aliyun configure ... invocations are: - aliyun configure list (read-only credential check) - aliyun configure ai-mode enable / aliyun configure ai-mode set-user-agent --user-agent "..." / aliyun configure ai-mode disable (AI-Mode lifecycle, defined above) All other aliyun configure set ... / aliyun configure delete ... / aliyun configure ... forms are forbidden. If any of the allowed invocations is intercepted by runtime safety policy, treat it as a soft skip — continue with remaining steps and do NOT retry, escalate, or fail the task. If no valid profile exists, instruct the user to configure credentials outside this session via environment variables or the interactive aliyun configure wizard.

Rules

[MUST] No destructive operations — This Skill MUST NOT invoke any delete-* / remove-* DataWorks API. Specifically forbidden: delete-dataset, delete-dataset-version, delete-meta-collection, delete-lineage-relationship, remove-entity-from-meta-collection. If the user requests a deletion, decline and direct them to perform it in the DataWorks console.

[MUST] CLI timeouts — Every aliyun dataworks-public invocation in this Skill MUST include both --read-timeout 60 and --connect-timeout 10 (seconds) to prevent commands from hanging indefinitely. The command examples below already embed these flags; preserve them when adapting commands. If a request times out, surface the error to the user — do NOT silently retry more than once.

[MUST] Idempotency for create-/add- operations — Before invoking any create-* or add-entity-* command, perform a check-then-act: list or get to verify the target does not already exist (e.g. before create-dataset call list-datasets and match by --name + --project-id; before add-entity-into-meta-collection call list-entities-in-meta-collection and match by entity id). If a previous attempt already succeeded, return the existing resource id instead of creating a duplicate. On retry after a transient error, prefer re-checking state over blindly re-issuing the create.

[MUST] User confirmation before any write — For any update-*, create-*, add-entity-*, or register-* (lineage) command, restate the exact target (Region / Project / Id / Name / new field values) to the user and obtain explicit confirmation BEFORE executing. Do not assume defaults; do not chain multiple writes without intermediate confirmation when the user has not pre-approved the full plan.

All CLI flags use kebab-case (lowercase with hyphens). Always use exactly the flag names shown in the command examples below. Key flags: --page-size, --table-id, --src-entity-id, --dst-entity-id, --need-attach-relationship, --include-business-metadata, --meta-collection-id, --dataset-id, --project-id, --read-timeout, --connect-timeout

Entity IDs follow ${EntityType}:${InstanceId}:${CatalogId}:${DatabaseName}:${SchemaName}:${TableName}. See references/entity-id-formats.md. Common MaxCompute: maxcompute-table:::project_name::table_name (no schema) or maxcompute-table:::project_name:schema_name:table_name (with schema). When user gives project.table, try no-schema first; if not found, retry with default schema.

Parameter confirmation — Confirm all user-customizable parameters (RegionId, entity IDs, etc.) before executing. Do NOT assume defaults.

Permission errors — Read references/ram-policies.md, guide the user to grant permissions, and wait for confirmation before retrying.

Commands

All commands require --region <RegionId> and the timeout pair --read-timeout 60 --connect-timeout 10. The user-agent is set globally via AI-Mode in the Prerequisites section, so no per-command --user-agent flag is needed below. All list commands support --page-number and --page-size.

aliyun dataworks-public list-entities-in-meta-collection --region <RegionId> --id <CollectionId> --page-size 20 --read-timeout 60 --connect-timeout 10

# Add entity into collection (write). Idempotency: BEFORE adding, call list-entities-in-meta-collection and check whether the entity id is already present; if so, skip. Removal is out of scope.
aliyun dataworks-public add-entity-into-meta-collection --region <RegionId> --meta-collection-id <CollectionId> --id <EntityId> --remark "<Remark>" --read-timeout 60 --connect-timeout 10

Tips

• Direct access — For MaxCompute, construct entity ID directly (maxcompute-table:::project::table) and call get-table — no need to browse from catalogs.
• Lineage direction — --src-entity-id = downstream, --dst-entity-id = upstream. For full impact analysis, recursively query each downstream entity to trace multi-level lineage (ODS->DWD->DWS->ADS).
• Schema fallback — If MaxCompute table not found, retry with :default: schema (three-level model).
• Limits — Max 20 versions per dataset; Album operations require AliyunDataWorksFullAccess or creator/admin; max 2000 datasets per tenant.
• Deletions — Out of scope. If the user asks to delete a dataset/version/collection/lineage relationship or remove an entity from a collection, decline and tell them to use the DataWorks console.
• Retry safely — When a write times out or returns an ambiguous error, do NOT blindly retry. Re-check state with the matching list-* / get-* first to detect partial success, then decide whether to retry or accept.
