+| source_storage_duration_value | <i class="fa-solid fa-hashtag" title="Numeric" aria-label="Numeric"></i> | How long was the source material stored, prior to this sample being processed? For assays applied to tissue sections, this would be how long the tissue section (e.g., slide) was stored, prior to the assay beginning (e.g., imaging). For assays applied to suspensions such as sequencing, this would be how long the suspension was stored before library construction began. |  |
+| source_storage_duration_unit <span style="color:red" title="Required" aria-label="Required">*</span> | <i class="fa-solid fa-circle-nodes" title="Allowable Value" aria-label="Allowable Value"></i> | The time duration unit of measurement | ```hour``` ```month``` ```day``` ```minute``` ```year``` |

+| contributors_path | <i class="fa-solid fa-font" title="Textfield" aria-label="Textfield"></i> | The path to the file with the ORCID IDs for all contributors of this dataset (e.g., "./extras/contributors.tsv" or "./contributors.tsv"). This is an internal metadata field that is just used for ingest. |  |
+| data_path | <i class="fa-solid fa-font" title="Textfield" aria-label="Textfield"></i> | The top level directory containing the raw and/or processed data. For a single dataset upload this might be "." where as for a data upload containing multiple datasets, this would be the directory name for the respective dataset. For instance, if the data is within a directory called "TEST001-RK" use syntax "./TEST001-RK" for this field. If there are multiple directory levels, use the format "./TEST001-RK/Run1/Pass2" in which "Pass2" is the subdirectory where the single dataset's data is stored. This is an internal metadata field that is just used for ingest. |  |
+| antibodies_path | <i class="fa-solid fa-font" title="Textfield" aria-label="Textfield"></i> | This is the location of the antibodies.tsv file relative to the root of the top level of the upload directory structure. This path should begin with "." and would likely be something like "./extras/antibodies.tsv". |  |
+| number_of_antibodies | <i class="fa-solid fa-hashtag" title="Numeric" aria-label="Numeric"></i> | Number of antibodies |  |
+| number_of_channels | <i class="fa-solid fa-hashtag" title="Numeric" aria-label="Numeric"></i> | Number of fluorescent channels imaged during each cycle. |  |

For Cell DIVE a biomarker imaging round consists of 1. staining of a biomarker via secondary detection or direct conjugate and 2. dye inactivation. |  |
+| number_of_total_imaging_rounds | <i class="fa-solid fa-hashtag" title="Numeric" aria-label="Numeric"></i> | The total number of acquisitions performed on microscope to collect autofluorescence/background or stained signal (e.g., histology). |  |
+| slide_id | <i class="fa-solid fa-font" title="Textfield" aria-label="Textfield"></i> | A unique ID denoting the slide used. This allows users the ability to determine which tissue sections were processed together on the same slide. It is recommended that data providers prefix the ID with the center name, to prevent values overlapping across centers. |  |
+| cell_boundary_marker_or_stain <span style="color:red" title="Required" aria-label="Required">*</span> | <i class="fa-solid fa-circle-nodes" title="Allowable Value" aria-label="Allowable Value"></i> | If a marker or stain was used to identify all cell boundaries in the tissue, then the name of the marker or stain should be included here. The name of the antibody-targeted molecule marker or non-antibody targeted molecule stain included here must be identical to what is found in the imaging data. For example, with the PhenoCycler, this name must match the value found in the XPD output file. If multiple marker or stains are used to identify all cell boundaries, then a comma separated list should be used here. | ```NAKATPASE``` ```CD298``` ```Not applicable``` |
+| nuclear_marker_or_stain <span style="color:red" title="Required" aria-label="Required">*</span> | <i class="fa-solid fa-circle-nodes" title="Allowable Value" aria-label="Allowable Value"></i> | For markers, an antibody-targetted molecule present in or around the cell nucleus, the protein or gene symbol that identifies the antibody target that is used as the nuclear marker. This symbol must match the antibody target that is either generated from the panel used or entered with custom panels. Preferably, if using a custom antibody marker, this symbol should be the HGNC symbol (https://www.genenames.org/).   For non-protein targets this is the stain name (e.g., DAPI) and, when appropriate, associated staining kit and vendor. For the PhenoCycler, this symbol must match the value found in the XPD output file. | ```DAPI``` ```Not applicable``` |
+| metadata_schema_id | <i class="fa-solid fa-font" title="Textfield" aria-label="Textfield"></i> | The string that serves as the definitive identifier for the metadata schema version and is readily interpretable by computers for data validation and processing. Example: 22bc762a-5020-419d-b170-24253ed9e8d9 |  |

+| parent_sample_id | <i class="fa-solid fa-font" title="Textfield" aria-label="Textfield"></i> | Unique HuBMAP or SenNet identifier of the sample (i.e., block, section or suspension) used to perform this assay. For example, for a RNAseq assay, the parent would be the suspension, whereas, for one of the imaging assays, the parent would be the tissue section. If an assay comes from multiple parent samples then this should be a comma separated list. Example: HBM386.ZGKG.235, HBM672.MKPK.442 or SNT232.UBHJ.322, SNT329.ALSK.102 |  |
+| lab_id | <i class="fa-solid fa-font" title="Textfield" aria-label="Textfield"></i> | A locally assigned identifier provided by the data provider for the dataset. It is used to reference an external metadata record that may be maintained independently, enabling traceability and supporting provenance tracking. Example: Visium_9OLC_A4_S1 |  |
+| preparation_protocol_doi <span style="color:red" title="Required" aria-label="Required">*</span> | <i class="fa-solid fa-font" title="Textfield" aria-label="Textfield"></i> | DOI for the protocols.io page that describes the assay or sample procurment and preparation. For example for an imaging assay, the protocol might include staining of a section through the creation of an OME-TIFF file.

For instance, if the data is within a directory called "TEST001-RK" use syntax "./TEST001-RK" for this field. If there are multiple directory levels, use the format "./TEST001-RK/Run1/Pass2" in which "Pass2" is the subdirectory where the single dataset's data is stored. This is an internal metadata field that is just used for ingest. |  |
+| antibodies_path | <i class="fa-solid fa-font" title="Textfield" aria-label="Textfield"></i> | This is the location of the antibodies.tsv file relative to the root of the top level of the upload directory structure.
