+# Token source status for tasksource-jev
+
+Checked on 23 September 2026 with the current `datasets` loader and a small
+end-to-end Tasksource recast. The release admits token tasks only when their
+source splits and label names can be checked and their ontology has 2–32
+readable choices. The build report covers other Tasksource source failures.
+
+| Tasksource source | Status | Work needed |
+|---|---|---|
+| `conll2003/ner_tags` | Included via [tomaarsen/conll2003](https://huggingface.co/datasets/tomaarsen/conll2003). | The original loader uses a forbidden script. The data-only copy retains the 14,041/3,250/3,453 train/dev/test counts and nine BIO NER labels. |
+| `wnut_17/wnut_17` | Included via [flaitenberger/wnut_17](https://huggingface.co/datasets/flaitenberger/wnut_17). | The original loader uses a forbidden script. The data-only copy retains the 3,394/1,009/1,287 splits and 13 BIO labels. |
+| `conll2003/pos_tags` | Excluded. | The original loader uses a forbidden script. The checked copy has 47 POS labels, above the current 32-choice gate. A curated smaller ontology would change the task and needs a separate design. |
+| `ncbi_disease/ncbi_disease` | Excluded. | The original loader uses a forbidden script. A checked data-only copy has 2,930/489/539 rows rather than the source card's 5,433/924/941, so equivalence is unverified. Find or make a faithful data-only export. |
+| `jnlpba/jnlpba` | Excluded. | The original loader uses a forbidden script. Find or make a faithful data-only export and verify its labels and splits. |
+| `ontonotes_english/SpeedOfMagic--ontonotes_english` | Excluded. | Tasksource requests an obsolete config name. The current default config has raw integer NER labels without `ClassLabel.names`; restore and verify the ontology before recasting. |
+| `few-nerd/supervised` | Excluded. | It loads, but its fine-grained ontology exceeds the 32-choice gate. |
+| `multilingual/xglue/ner`, `multilingual/xglue/pos` | Excluded. | Their original loader uses a forbidden script. Find faithful data-only exports with readable label metadata. |
+| `multilingual/universal_dependencies/pos` and English dependency-relation configurations | Excluded. | The registered `universal_dependencies` source is unavailable. Find a faithful export and verify POS/dependency label order. |
+| `multilingual/multiconer_v2` | Excluded. | Its original loader uses a forbidden script. Find a faithful data-only export with readable label metadata. |
+| FINER-139, MAPA, acronym identification, chunking | Not enabled. | Inspect label semantics, ontology size, and source compatibility before adding them. |
+
+These are release decisions, not claims that the underlying datasets are
+incorrect. Where a mirror is used, the original Tasksource identifier remains
+in `source`; this table records the actual data repository.
