| 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 <span style="white-space: pre;"> </span>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 | |

-- IVOA.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 | |

<span style="background-color: transparent;">-- IVOA.CarlosRodrigo (2019-02-25)</span>

<span style="background-color: transparent;"> I think this would be nice and useful to link one (or several) bibliografic reference(s) to the data. <br /></span>

| 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 | |

| 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 :  |
| WG and Semantics group decision | |
| TCG Validation (date) | |
| any other useful feature | |

| 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 | |

<span style="background-color: transparent;">Discussion paragraph : </span> -- IVOA.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 | |
