+
+Note that some URIs are not handled by the extended prefix map inside the converter, so if you want
+to pass those through, use ``passthrough=True`` like in
+
+.. code-block:: python
+
+ converter.pd_compress(df, column="uri", target_column="curie", passthrough=True)

+Expand CURIEs
+~~~~~~~~~~~~~
+In order to demonstrate bulk operations using :meth:`curies.Converter.pd_expand`,
+we construct a small dataframe used in conjunction with the OBO converter (which
+only includes OBO Foundry ontology URI prefix expansions):
+
+.. code-block:: python
+
+ import curies
+ import pandas as pd
+
+ df = pd.DataFrame({"curie": [
+ "GO:0000001",
+ "skos:exactMatch",
+ ]})
+
+ converter = curies.get_obo_converter()
+ converter.pd_expand(df, column="curie", target_column="uri")
+
+=============== =========================================
+curie uri
+=============== =========================================
+GO:0000001 http://purl.obolibrary.org/obo/GO_0000001
+skos:exactMatch
+=============== =========================================
+
+Note that since ``skos`` is not in the OBO Foundry extended prefix map, no results are placed in
+the ``uri`` column. If you wan to pass through elements that can't be expanded, you can use
+``passthrough=True`` like in:
+
+.. code-block:: python
+
+ converter.pd_expand(df, column="curie", target_column="uri", passthrough=True)
+
+=============== =========================================
+curie uri
+=============== =========================================
+GO:0000001 http://purl.obolibrary.org/obo/GO_0000001
+skos:exactMatch skos:exactMatch
+=============== =========================================
+
+Alternatively, chaining together multiple converters (such as the Bioregistry) will yield better results
+
+.. code-block:: python
+
+ import curies
+ import pandas as pd
+
+ df = pd.DataFrame({"curie": [
+ "GO:0000001",
+ "skos:exactMatch",
+ ]})
+
+ converter = curies.chain([
+ curies.get_obo_converter(),
+ curies.get_bioregistry_converter(),
+ ])
+ converter.pd_expand(df, column="curie", target_column="uri")
+
+=============== ==============================================
+curie uri
+=============== ==============================================
+GO:0000001 http://purl.obolibrary.org/obo/GO_0000001
+skos:exactMatch http://www.w3.org/2004/02/skos/core#exactMatch
+=============== ==============================================
+
+Standardizing Prefixes
+~~~~~~~~~~~~~~~~~~~~~~
+The `Gene Ontology (GO) Annotations Database `_
+distributes its file where references to proteins from the `Universal Protein Resource (UniProt)
+`_ use the prefix ``UniProtKB``. When using the Bioregistry's extended prefix map,
+these prefixes should be standardized to ``uniprot`` with :meth:`curies.Converter.pd_standardize_prefix`.
+This can be done in-place with the following:
+
+.. code-block:: python
+
+ import pandas
+ import curies
+
+ # the first column represents the prefix for the protein,
+ # called "DB" in the schema. This is where we want to upgrade
+ # `UniProtKB` to `uniprot`
+ df = pd.read_csv(
+ "http://geneontology.org/gene-associations/goa_human.gaf.gz",
+ sep="\t",
+ comment="!",
+ header=None,
+ )
+
+ converter = curies.get_bioregistry_converter()
+ converter.pd_standardize_prefix(df, column=0)
+
+The ``target_column`` keyword can be given if you don't want to overwrite the original.
+
+Standardizing CURIEs
+~~~~~~~~~~~~~~~~~~~~~~
+Using the same example data from GO, the sixth column contains CURIE for references such as
+`GO_REF:0000043 `_. When using the Bioregistry's extended prefix map,
+these CURIEs' prefixes should be standardized to ``go.ref`` with :meth:`curies.Converter.pd_standardize_curie`.
+This can be done in-place with the following:
+
+.. code-block:: python
+
+ import pandas
+ import curies
+
+ df = pd.read_csv(
+ "http://geneontology.org/gene-associations/goa_human.gaf.gz",
+ sep="\t",
+ comment="!",
+ header=None,
+ )
+
+ converter = curies.get_bioregistry_converter()
+ converter.pd_standardize_curie(df, column=5)
+
+The ``target_column`` keyword can be given if you don't want to overwrite the original.
