It has two components that are used conjointly: an algorithm for automatic schema construction, and an interactive workflow for editing the schema. The schema construction algorithm takes as input sets of sample nodes and constructs a shape constraint for every sample set. It can be parametrized by a schema pattern that defines structural requirements for the schema to be constructed. Schema patterns are also used to feed the algorithm with relevant information about the dataset coming from a dom","authors_text":"Daniel Fern\\'andez \\'Alvarez, Iovka Boneva, J\\'er\\'emie Dusart, Jose Emilio Labra Gayo","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.DB","submitted_at":"2019-07-24T10:47:21Z","title":"Semi Automatic Construction of ShEx and SHACL Schemas"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1907.10603","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:2327ccddb519f04a3ec04b0182ba025d9769df84c15abbfbff79d643a327c950","target":"record","created_at":"2026-05-17T23:39:34Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"e1f2dd3d9742baba89902f815fc95cf1abb34ff2af708c2cba05cb9f381f8152","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.DB","submitted_at":"2019-07-24T10:47:21Z","title_canon_sha256":"221a1f85fb1fb2c8070a109588819f6bb17c39f27c82f47bafda8dc6cbc20142"},"schema_version":"1.0","source":{"id":"1907.10603","kind":"arxiv","version":1}},"canonical_sha256":"9b59a3918e54e65305648db077add1bc96ddc75700aa39a5c5338830c3feca3d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9b59a3918e54e65305648db077add1bc96ddc75700aa39a5c5338830c3feca3d","first_computed_at":"2026-05-17T23:39:34.962174Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:39:34.962174Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"GtvMDIMf8eo1qm8MSpiSfI3oNdRGEFwY3YnxhrxsJwSsuXDelxh9a/y4JBI4g9mIMJk2/WX/NnZ3jUrwNMBmCg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:39:34.962866Z","signed_message":"canonical_sha256_bytes"},"source_id":"1907.10603","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2327ccddb519f04a3ec04b0182ba025d9769df84c15abbfbff79d643a327c950","sha256:4e2effb7dbd7b3fe4c99532f86538281fc10c4ecb44e2e5332f8d00b850d9a0c"],"state_sha256":"9ca26f2241195e23209e2c8eda32cff1fe80d3b42cbb5caab867368e62affddd"}
