PyLiPD User API
The following describes the main classes that makes up PyLiPD. Most users will only interface with the functionalies contained in these classes.
LiPD (pylipd.lipd.LiPD)
- class pylipd.lipd.LiPD(graph=None)[source]
The LiPD class describes a LiPD (Linked Paleo Data) object. It contains an RDF Graph which is serialization of the LiPD data into an RDF graph containing terms from the LiPD Ontology <http://linked.earth/Ontology/release/core/1.2.0/index-en.html> How to browse and query LiPD objects is described in a short example below.
Examples
In this example, we read an online LiPD file and convert it into a time series object dictionary.
from pylipd.lipd import LiPD lipd = LiPD() lipd.load(["https://lipdverse.org/data/LCf20b99dfe8d78840ca60dfb1f832b9ec/1_0_1//Nunalleq.Ledger.2018.lpd"]) ts_list = lipd.get_timeseries(lipd.get_all_dataset_names()) for dsname, tsos in ts_list.items(): for tso in tsos: if 'paleoData_variableName' in tso: print(dsname+': '+tso['paleoData_variableName']+': '+tso['archiveType'])

- get_dataset_properties()[source]
Get a list of unique properties attached to a dataset.
Note: Some properties will return another object (e.g., ‘publishedIn’ will give you a Publication object with its own properties) Note: Not all datasets will have the same available properties (i.e., not filled in by a user)
- Returns:
clean_list – A list of avialable properties that can queried
- Return type:
list
Examples
from pylipd.utils.dataset import load_dir lipd = load_dir(name='Pages2k') dataset_properties = lipd.get_dataset_properties() print(dataset_properties)

- get_ensemble_tables(dsname=None, ensembleVarName=None, ensembleDepthVarName='depth')[source]
Gets ensemble tables from the LiPD graph
- Parameters:
dsname (str) – The name of the dataset if you wish to analyse one at a time (Set to “.*” to match all datasets with a common root)
ensembleVarName (None or str) – ensemble variable name. Default is None, which searches for names that contain “year” or “age” (Set to “.*” to match all ensemble variable names)
ensembleDepthVarName (str) – ensemble depth variable name. Default is ‘depth’ (Set to “.*” to match all ensemble depth variable names)
- Returns:
ensemble_tables – A dataframe containing the ensemble tables
- Return type:
dataframe

- get_model_properties()[source]
Get all the properties associated with a model
- Returns:
A list of unique properties attached to models
- Return type:

- get_timeseries(dsnames, to_dataframe=False)[source]
Get Legacy LiPD like Time Series Object (tso)
- Parameters:
dsnames (list) – array of dataset id or name strings
to_dataframe (bool {True; False}) – Whether to return a dataframe along the dictionary. Default is False
- Returns:
ts (dict) – A dictionary containing Time Series Object
df (Pandas.DataFrame) – If to_dataframe is set to True, returns a queriable Pandas DataFrame

- Parameters:
dsname (str, optional) – The name of the dataset for which to return the timeseries information. The default is None.
mode (paleo, chron) – Whether to retrun the information stored in the PaleoMeasurementTable or the ChronMeasurementTable. The default is ‘paleo’.
- Raises:
ValueError – Need to select either ‘chron’ or ‘paleo’
- Returns:
qres_df – A pandas dataframe returning the properties in columns for each series stored in a row of the dataframe
- Return type:
pandas.DataFrame

LiPDSeries (pylipd.lipd_series.LiPDSeries)
- class pylipd.lipd_series.LiPDSeries(graph=None)[source]
The LiPD Series class describes a collection of LiPD (Linked Paleo Data) variables. It contains an RDF Graph which is serialization of LiPD variables into an RDF graph containing terms from the LiPD Ontology <http://linked.earth/Ontology/release/core/1.2.0/index-en.html>. Each LiPD Variable is also associated with the LiPD itself so it can be deserialized into the original LiPD format. How to browse and query the LiPD variables is described in a short example below.
Examples
In this example, we read an online LiPD file and convert it into a time series object dictionary.
from pylipd.lipd_series import LiPDSeries lipd = LiPD() lipd.load(["https://lipdverse.org/data/LCf20b99dfe8d78840ca60dfb1f832b9ec/1_0_1//Nunalleq.Ledger.2018.lpd"]) lipd_series = lipd.to_lipd_series()
