+WGs can be created by any member of the LinkedEarth community to discuss topics of interest. The rationale for such WGs is that the paleo community is incredibly diverse, and what matters to a coral geochemist may be very different than what matters to a dendrochronologist. That being said, both might care about similar things.  The WGs should just span the interests of the community and how they intersect.

−
−	~~== Getting Started with standards==~~
−
−	~~Getting started with creating a standard for the entire community can be seen as a daunting task. The most obvious questions are "what does a standard actually look like?", "Where do I start?".~~
−
−	~~=== Where do I start?===~~
−
−	The ultimate goal of LinkedEarth is to provide scientists with tools to make better science, including allowing scientists to upload the metadata they need to make their science reproducible, allows complex queries on the system to easily retrieve datasets, and provide packages in R and Python for the analysis of these datasets using the standards developed by the community.
−
−	~~==== Uploading the needed metadata ====~~
−
−	The strength and appeal of the field of paleoclimatology reside in its diversity. This community relies on the work of geochemists, geologists, computer modelers, statisticians ... to understand past climates. This diversity is also reflected in the datasets generated within the community. Therefore, a one-size-fit-all template for all paleoclimate datasets isn't useful. The LinkedEarth wiki allows to store the metadata each community needs to represent their data. For instance, the cleaning methodology may be important to the foraminiferal Mg/Ca community but completely irrelevant to the tree-ring community. Therefore, one possible way to create a standard is to ask oneself: "What pieces of metadata would I require to reproduce this particular dataset and therefore which one should I provide for my own datasets?"
−
−	Some of these metadata will be standard across all archives (i.e., geographic coordinates, publication information). Some will be archive (and even observation)-specific. See [[:Category:Marine_Sediment_Working_Group \| here]] for the beginning of a discussion on foraminiferal Mg/Ca.
−
−	~~==== Querying the datasets ====~~
−
−	Another way to think about the essential/recommended/optional metadata is to think about the kind of queries one would want to enable for their research. For instance, [http://linked.earth/wp-content/uploads/2016/01/Khider_AGUFall16.pdf Testing the Millennial-Scale Solar-Climate Connection in the Indo-Pacific Warm Pool] required the following query and associated metadata:
−
−	~~{\| class="wikitable"~~
−	\|-
−	~~! Query \|\| Required Metadata~~
−	\|-
−	\| SST-sensitive proxies (i.e. Mg/Ca, Uk37 and TEX86) \|\| Needed a property describing the proxy observations as well as a standard to express the concept of Mg/Ca, TEX86 and UK37. This need gave rise to [[:Property:OnProxyObservationProperty_©]] and terms in the ontology [[:Category:ProxyObservation_©]] to describe these concepts.
−	\|-
−	\| Holocene data (0-10ka) spanning at least 5kyr \|\| Needed a property describing the concept of [[Age]], giving rise to [[:Property:OnInferredVariableProperty]]. An ontology for [[:Category:InferredVariable_ ©]] is in progress. It also became obvious that we needed to standardize the way to represent time and the units of time. Furthermore, since the wiki doesn't read the content of the csv file, some metadata about the values stored in the .csv file were also needed. We therefore created the following properties: [[:Property:HasMinValue]], [[:Property:HasMaxValue]],[[:Property:HasMeanValue]].
−	\|-
−	~~\| In the IndoPacific Warm Pool \|\| We needed to query the dataset by latitude/longitude~~
−	\|}
−
−	Other types of basic query include querying for a particular publication, using either the DOI, title, journal, authors, and querying by [[:Category:ProxyArchive_ © \| archiveType]]. The later is currently used to obtain the maps under each archive category (for example, [[:Category:MarineSediment \| marine sediments]]). Enter the queries you'd like to perform, and the metadata required to perform them.
−
−	~~==== Data analysis ====~~
−
−	~~Finally, this problem can be approached from a data analysis point-of-view. "Given my interest, what are the required information I would need to perform my analysis?"~~
−
−	For instance, if all is know about a dataset is the geographical coordinates from which the archive was taken, then the only possible analysis is to create a location map of said archive (with or without its nearest neighbor contained in the database.) On the other hand, if an age and inferred variable are contained within the PaleoDataTable, the resulting time series can be used for correlation analysis and spectral analysis. However, without the raw data, it would be impossible to recalibrate the record using updated techniques, further limiting its usefulness.
−
−	~~For the Holocene study, the Dataset had to contain the raw radiocarbon measurements for use with Bchron.~~
−
−	~~== Prior discussions on Standards Developments in Paleoclimatology ==~~
−
−	We welcome any summaries of prior discussions on data standards you may have had at meetings, workshops. To do so, either link to a document that you have uploaded on the wiki or create a new page and list it below. Sign and data using the following notation: <pre>~~~~</pre>
