Hi,

I have trouble finding a table that links the SectionDataSet IDs to metadata like the gene name and the age.

for example: SectionDataSetID 100081428 corresponds to Tcf21, P4 as can be seen in [Experiment Detail :: Allen Brain Atlas: Mouse Brain](https://mouse.brain-map.org/experiment/show/100081428)

Here is the context:

- I listed the 20 274 SectionDataSetIDs available in the development AGEA adapting [the method provided in a conversation from this forum](https://community.brain-map.org/t/downloading-comprehensive-list-of-sectiondatasets-for-ish-data/1521).
- Then I downloaded the energy grids using the `allensdk.api.queries.grid_data_api.GridDataApi`
- However i only have the sectionDataSet ID for each grid and i need for further analysis the name of the gene and the developmental stage.

In fact, it is possible to get this information for the Adult AGEA adapting [this Notebook from the Allen Institute](https://github.com/AllenInstitute/open_dataset_tools/blob/main/example_notebooks/Accessing_Allen_Mouse_Brain_Atlas_Data.ipynb), (`open_dataset_tools.aba_mouse_utils.get_atlas_metadata` function).

How can I get the same metadata for the Developing AGEA?
