# Cookbook
+These quickstart examples gloss over a lot of details in the API. The canonical
+API documentation (generated from the OpenAPI specification) is available at
+<https://api.fatcat.wiki/redoc>.
+
+The first two simple cookbook examples here include full headers. Later
+examples only show python client library code snippets.
+
+### Lookup Fulltext URLs by DOI
+
+Often you have a DOI or other paper identifier and want to find open copies of
+the paper to read. In fatcat terms, you want to lookup a release by external
+identifier, then sort through any associated file entities to find the best
+files and URLs to download. Note that the [Unpaywall](https://unpaywall.org)
+API is custom designed for this task and you should look in to using that
+instead.
+
+This is read-only task and requires no authentication. The simple summary is
+to:
+
+1. GET the release lookup endpoint with the external identifier as a query
+ parameter. Also set the `hide` parameter to elide unused fields, and the
+ `expand` parameter to `files` to include related files in a single request.
+2. If you get a hit (HTTP 200), sort through the `files` field (an array) and
+ for each file the `urls` field (also an array) to select the best URL(s).
+
+The URL to use would look like
+<https://api.fatcat.wiki/v0/release/lookup?doi=10.1088/0264-9381/19/7/380&expand=files&hide=abstracts,refs>
+in a browser. The query parameters should be URL encoded (eg, the DOI `/`
+characters replaced with with `%20`), but almost all HTTP tools and libraries
+will do this automatically.
+
+The raw HTTP request would look like:
+
+ GET /v0/release/lookup?doi=10.1088%2F0264-9381%2F19%2F7%2F380&expand=files&hide=abstracts%2Crefs HTTP/1.1
+ Accept: */*
+ Accept-Encoding: gzip, deflate
+ Connection: keep-alive
+ Host: api.fatcat.wiki
+ User-Agent: HTTPie/0.9.8
+
+And the response (with some headers removed and JSON body paraphrased):
+
+ HTTP/1.1 200 OK
+ Connection: keep-alive

+ }

+ ],
+ }
+
+An `httpie` and `jq` one-liner to grap the first URL would be:
+
+ http https://api.fatcat.wiki/v0/release/lookup doi==10.1088/0264-9381/19/7/380 expand==files hide==abstracts,refs | jq '.files[0].urls[0].url' -r
+
+Using the python client library (`fatcat-openapi-client`), you might do
+something like:
+
+```python
+import fatcat_openapi_client
+from fatcat_openapi_client.rest import ApiException
+
+conf = fatcat_openapi_client.Configuration()
+conf.host = "https://api.fatcat.wiki/v0"
+api = fatcat_openapi_client.DefaultApi(fatcat_openapi_client.ApiClient(conf))
+doi = "10.1088/0264-9381/19/7/380"
+
+try:
+ r = api.lookup_release(doi=doi, expand="files", hide="abstracts,refs")
+except ApiException as ae:
+ if ae.status == 404:
+ print("DOI not found!")
+ return
+ else:
+ raise ae
+
+print("Fatcat release found: https://fatcat.wiki/release/{}".format(r.ident))
+
+for f in r.files:
+ if f.mimetype != 'application/pdf':
+ continue
+ for u in r.urls:
+ if u.rel == 'webarchive' and '//web.archive.org/' in u.url:
+ print("Wayback PDF URL: {}".format(u.url)
+ return
+
+print("No Wayback PDF URL found")
+```
+
+A more advanced lookup tool would check for sibling releases under the same
+work and provide both alternative links ("no version of record available, but
+here is the pre-print") and notify the end user about any updates or
+retractions to the work as a whole.
+
+### Creating an Entity
+
+Let's use a container (journal) entity as a simple example of mutation of the
+catalog. This assumes you already have an editor account and API token, both
+obtained through the web interface.
+
+In summary:
+
+1. Create (POST) an editgroup
+2. Create (POST) the container entity as part of editgroup
+3. Submit the editgroup for review
+4. (privileged) Accept the editgroup
+
+See the [API docs](https://api.fatcat.wiki/redoc#section/Authentication) for
+full details of authentication.
+
+To create an editgroup, the raw HTTP request (to
+<https://api.fatcat.wiki/v0/editgroup>) and response would look like:
+
+ POST /v0/editgroup HTTP/1.1
+ Accept: application/json, */*
+ Accept-Encoding: gzip, deflate
+ Authorization: Bearer AgEPZGV2LmZhdGNhdC53aWtpAhYyMDE5MDEwMS1kZXYtZHVtbXkta2V5AAImZWRpdG9yX2lkID0gYWFhYWFhYWFhYWFhYmt2a2FhYWFhYWFhYWkAAht0aW1lID4gMjAxOS0wMS0wOVQwMDo1Nzo1MloAAAYgnroNha1hSftChtxHGTnLEmM/pY8MeQS/jBSV0UNvXug=

+ "editor_id": "4vmpwdwxxneitkonvgm2pk6kya"
+ }
+
+It is important to parse the response to get the `editgroup_id`. Next POST to
+<https://fatcat.wiki/v0/editgroup/EDITGROUP_ID/container> (with the
+`editgroup_id` substituted) and the JSON container entity as the body:

+ "revision": "796429d2-44a4-4ece-a9b2-e80edcd4277a"
+ }
+
+To submit an editgroup, use the update endpoint with the `submit` query
+parameter set to `true`. The body should be the editgroup object (as JSON), but
+is mostly ignored:
+
+
+ PUT /v0/editgroup/aqhyo2ulmzfbrewn3rv7dhl65u?submit=true HTTP/1.1
+ Accept: application/json, */*
+ Accept-Encoding: gzip, deflate

+ "submitted": "2019-09-17T23:37:06.288434Z"
+ }
+
+Lastly, if your editor account as the `admin` role, you can "accept" the
+editgroup using the accept endpoint:
+
+
+ POST /v0/editgroup/aqhyo2ulmzfbrewn3rv7dhl65u/accept HTTP/1.1
+ Accept: */*
+ Accept-Encoding: gzip, deflate
+ Authorization: Bearer AgEPZGV2LmZhdGNhdC53aWtpAhYyMDE5MDEwMS1kZXYtZHVtbXkta2V5AAImZWRpdG9yX2lkID0gYWFhYWFhYWFhYWFhYmt2a2FhYWFhYWFhYWkAAht0aW1lID4gMjAxOS0wMS0wOVQwMDo1Nzo1MloAAAYgnroNha1hSftChtxHGTnLEmM/pY8MeQS/jBSV0UNvXug=

+
+ {
+ "message": "horray!",

+ }
+
+This whole exchange is, of course, must faster with the python library:
+
+```python

+
+conf = fatcat_openapi_client.Configuration()
+conf.host = "https://api.fatcat.wiki/v0"
+conf.api_key_prefix["Authorization"] = "Bearer"
+conf.api_key["Authorization"] = "AgEPZGV2LmZhdGNhdC53aWtpAhYyMDE5MDEwMS1kZXYtZHVtbXkta2V5AAImZWRpdG9yX2lkID0gYWFhYWFhYWFhYWFhYmt2a2FhYWFhYWFhYWkAAht0aW1lID4gMjAxOS0wMS0wOVQwMDo1Nzo1MloAAAYgnroNha1hSftChtxHGTnLEmM/pY8MeQS/jBSV0UNvXug="
+api = fatcat_openapi_client.DefaultApi(fatcat_openapi_client.ApiClient(conf))
+
+c = fatcat_openapi_client.ContainerEntity(
+ name="Test Journal",
+ issnl="1234-5678",
+)
+editgroup = api.create_editgroup(description="my test editgroup")
+c_edit = api.create_container(editgroup.editgroup_id, c)
+api.update_editgroup(editgroup.editgroup_id, submit=True)
+
+# only if you have permissions
+api.accept_editgroup(editgroup.editgroup_id)
+```
+
### Updating an Existing Entity
-1. Fetch (GET) the existing entity
+It is important to ensure that edits/updates are *idempotent*, in this case
+meaning that if you ran the same script twice in quick succession, no mutation
+or update would occur the second time. This is usually achieved by always
+fetching entities just before an edit and checking that updates are actually
+necessary.
+
+The basic process is to:
+
+1. Fetch (GET) or Lookup (GET) the existing entity. Check that edit is actually necessary!
2. Create (POST) a new editgroup
-3. Update (PUT) the entity, with the current revision number in the `prev` edit
- field, and the `editgroup_id` set
+3. Update (PUT) the entity
4. Submit (PUT) the editgroup for review
-5. Somebody (human or bot) with admin privileges will Accept (POST) the editgroup.
+
+Python example code:
+
+```python
+import fatcat_openapi_client
+from fatcat_openapi_client.rest import ApiException
+
+conf = fatcat_openapi_client.Configuration()
+conf.host = "https://api.fatcat.wiki/v0"
+conf.api_key_prefix["Authorization"] = "Bearer"
+conf.api_key["Authorization"] = "AgEPZGV2LmZhdGNhdC53aWtpAhYyMDE5MDEwMS1kZXYtZHVtbXkta2V5AAImZWRpdG9yX2lkID0gYWFhYWFhYWFhYWFhYmt2a2FhYWFhYWFhYWkAAht0aW1lID4gMjAxOS0wMS0wOVQwMDo1Nzo1MloAAAYgnroNha1hSftChtxHGTnLEmM/pY8MeQS/jBSV0UNvXug="
+api = fatcat_openapi_client.DefaultApi(fatcat_openapi_client.ApiClient(conf))
+
+new_name = "Classical and Quantum Gravity"
+c = api.get_container('j5iizqxt2rainmxg6nfmpg2ds4')
+if c.name == new_name:
+ print("Already updated!")
+ return
+
+c.name = new_name
+
+editgroup = api.create_editgroup(description="my test container editgroup")
+c_edit = api.update_container(editgroup.editgroup_id, c.ident, c)
+api.update_editgroup(editgroup.editgroup_id, submit=True)
+```
### Merging Duplicate Entities
-1. Fetch (GET) both entities
+Like other mutations, be careful that any merge oprations do not clobber the
+catalog if run multiple times.
+
+Summary:
+
+1. Fetch (GET) both entities. Ensure that merging is still required.
2. Decide which will be the "primary" entity (the other will redirect to it)
3. Create (POST) a new editgroup
4. Update (PUT) the "primary" entity with any updated metadata merged from the
other entity (optional), and the editgroup id set
5. Update (PUT) the "other" entity with the redirect flag set to the primary's
- identifier, with the current revision id (of the "other" entity) in the
- `prev` field, and the editgroup id set
+ identifier.
6. Submit (PUT) the editgroup for review
7. Somebody (human or bot) with admin privileges will Accept (POST) the editgroup.
-### Lookup Fulltext URLs by DOI
+Python example code:
+
+```python
+import fatcat_openapi_client
+from fatcat_openapi_client.rest import ApiException
-1. Use release lookup endpoint (GET) with the `doi` query parameter in
- URL-escaped format, with `expand=files`. You may want to `hide`
- `abstracts,references` for faster responses if you aren't interested in
- those fields.
-2. If a release hit is found, iterate over the linked `file` entities, and
- create a ranked list of URLs based on mimetype, URL "rel" type, file size,
- or host domain.
+conf = fatcat_openapi_client.Configuration()
+conf.host = "https://api.fatcat.wiki/v0"
+conf.api_key_prefix["Authorization"] = "Bearer"
+conf.api_key["Authorization"] = "AgEPZGV2LmZhdGNhdC53aWtpAhYyMDE5MDEwMS1kZXYtZHVtbXkta2V5AAImZWRpdG9yX2lkID0gYWFhYWFhYWFhYWFhYmt2a2FhYWFhYWFhYWkAAht0aW1lID4gMjAxOS0wMS0wOVQwMDo1Nzo1MloAAAYgnroNha1hSftChtxHGTnLEmM/pY8MeQS/jBSV0UNvXug="
+api = fatcat_openapi_client.DefaultApi(fatcat_openapi_client.ApiClient(conf))
-### Batch Insert New Entities (Bootstrapping)
+left = api.get_creator('iimvc523xbhqlav6j3sbthuehu')
+right = api.get_creator('lav6j3sbthuehuiimvc523xbhq')
-When bootstrapping a blank catalog, we need to insert 10s or 100s of millions
-of entities as fast as possible.
+# check that merge/redirect hasn't happened yet
+assert left.state == 'active' and right.state == 'active'
+assert left.redirect = None and right.redirect_id = None
+assert left.revision != right.revision
-1. Batch create (POST) a set of entities, with editgroup metadata included
+# decide to merge "right" into "left"
+if not left.orcid:
+ left.orcid = right.orcid
+if not left.surname:
+ left.surname = right.surname
+
+editgroup = api.create_editgroup(description="my test creator merge editgroup")
+left_edit = api.update_creator(editgroup.editgroup_id, left.ident, left)
+right_edit = api.update_creator(eidtgroup.editgroup_id, right.ident,
+ fatcat_openapi_client.CreatorEntity(redirect=left.ident))
+api.update_editgroup(editgroup.editgroup_id, submit=True)
+```
+
+### Batch Create Entities
+
+When importing large numbers (thousands) of entities, it can be faster to use
+the batch create operations instead of individual editgroup and entity
+creation. Using the batch endpoints requires care because the potential to
+pollute the catalog with bad entities (and the effort required to clean up) can
+be much larger.
+
+These methods always require the `admin` role, because they are the equivalent
+of creation and editgroup accept.
+
+It is not currently possible to do batch updates or deletes in a single
+request.
+
+The basic process is:
+
+1. Confirm that input entities should be created (eg, using identifier
+ lookups), and bundle into groups of 50-100 entities.
+2. Batch create (POST) a set of entities, with editgroup metadata included
along with list of entities (all of a single type). Entire batch is inserted
- and the editgroup accepted (requiring admin bits) in a single transaction.
+ in a single request.
+
+
+```python

+
+### Import New Files Linked to Releases

+Let's say you knew of many open access PDFs, including their SHA-1, size, and a URL:

+The process for adding these could be something like:
+
+1. For each row, check if file with SHA-1 exists; if so, skip
+2. For each row, lookup the release by DOI; if it doesn't exist, skip
+3. Transform into File entities
+3. Group entities into batches
+4. Submit batches to API
+
+There are multiple ways to structure code to do this. You may want to look at
+the `importer` class under `python/fatcat_tools/importers/common.py`, and other
+existing import scripts in that directory for a framework to structure this
+type of import.
+
+Here is a simpler example using only the python library:
+
+```python
+
+# TODO: actually test this code
+
+import sys
+import fatcat_openapi_client
+from fatcat_openapi_client import *
+from fatcat_openapi_client.rest import ApiException
+
+conf = fatcat_openapi_client.Configuration()
+conf.host = "https://api.fatcat.wiki/v0"
+conf.api_key_prefix["Authorization"] = "Bearer"
+conf.api_key["Authorization"] = "AgEPZGV2LmZhdGNhdC53aWtpAhYyMDE5MDEwMS1kZXYtZHVtbXkta2V5AAImZWRpdG9yX2lkID0gYWFhYWFhYWFhYWFhYmt2a2FhYWFhYWFhYWkAAht0aW1lID4gMjAxOS0wMS0wOVQwMDo1Nzo1MloAAAYgnroNha1hSftChtxHGTnLEmM/pY8MeQS/jBSV0UNvXug="
