Discussion Page for Datalink Update

Here are the new terms proposed to enrich the datalink. They should be discussed within the DAL WG. Feel free to suggest your terms here and provide feedback after usage , as data providers and client users.

Here below is a template for suggesting new terms .

you can copy this part and add your new requirement for terms .


Proposal associated_data
Proposed by Mireille Louys and FrancoisBonnarel
Date 2018-05-31
Rationale This branch is proposed to accomodate a description of the dataproduct-type pointed by the link target (for example when attached to a source in a catalog) Below we could find several dataproductypes flavors.
  associated_data:image , associated_data:spectrum, associated_data:time_series, associated_data:cube etc...
Feedback after usage  
  example 1 :source in an ESO catalog: several links to spectra of the object with semantics "associated_data:spectrum
  example 2: GAIA DR2 source : links to associated TimeSeries with semantics field "associated_data:timeseries
WG and Semantics group decision  
TCG Validation (date)  
any other useful feature  

Discussion paragraph :

-- MireilleLouys - 2018-05-31

If the type of the pointed dataset is expressed this way, this semantics field will help the client designer to send the link for the target dataset to an appropriate tool , via samp for instance.

Proposal data_documentation
Proposed by Alberto Micol
Date 2019-02-05
Rationale This branch is proposed to link documentation text to the data in a format defined via the "contentType" field
Feedback after usage  
  example 1 : a text giving some details on observation conditions can be attached to a dataset
WG and Semantics group decision  
TCG Validation (date)  
any other useful feature

-- CarlosRodrigo (2019-02-25)

I think this would be nice and useful to link one (or several) bibliografic reference(s) to the data.

Proposal metadata
Proposed by Markus Demleitner
Date 2019-02-06 original idea back to october 2015
Rationale This branch is proposed to link descriptive metadata to the main resource
Feedback after usage  
  example 1 : an ObsCore record or a Provenance Record can be attached to a dataset discovered another way
WG and Semantics group decision  
TCG Validation (date)  
any other useful feature  

Discussion paragraph :

Proposal fault
Proposed by Markus Demleitner
Date 2019-02-06 original idea back to october 2015
Rationale This branch for a Semantics field identifying that the table row generated an error
Feedback after usage  
  example 1 :

Proposal science_alternate
Proposed by Markus Demleitner
Date 2019-02-06 original idea back to october 2015
Rationale This branch for a link to a transformed dataset
Feedback after usage  
  example 1 : we link a calibrated image to a rebinned version of the same image
  example 1 : we link a calibrated image to a image with sky background removed
WG and Semantics group decision  
TCG Validation (date)  
any other useful feature  

Discussion paragraph : -- FrancoisBonnarel - 2019-02-06 We may wonder if this is not redondant (or partially redondant) with #derivation.

Proposal alt
Proposed by Markus Demleitner
Date 2019-02-06 original idea back to october 2015
Rationale This branch for a Semantics field identifying that this is the same dataset in another format
Feedback after usage  
  example 1 : an original spectrum given in FITS Format. The link with "alt" is for the same spectrum in VOTable or csv (according to content_type value)
WG and Semantics group decision  
TCG Validation (date)  
any other useful feature
