MetaSat: Metadata for Small Satellite Missions

Change Color Theme: This template is designed to use the built-in color themes in the newer versions of PowerPoint. To change the color theme, select the Design tab, then select the Colors drop-down list. The default color theme for this template is “Office”, so you can always return to that after trying some of the alternatives. Printing Your Poster: Once your poster file is ready, visit www.genigraphics.com to order a high-quality, affordable poster print. Every order receives a free design review and we can deliver as fast as next business day within the US and Canada. Genigraphics® has been producing output from PowerPoint® longer than anyone in the industry; dating back to when we helped Microsoft® design the PowerPoint® software.

It can be used to print any poster with a 1:1 aspect ratio. Replace the QR Code with a link to your complete research paper. We prefer: https://www.qrstuff.com (Genigraphics has no relationship) Always check the specific poster requirements with your conference organizer to confirm if this type of poster design is allowed. Multiple Layouts: Use the Layout dropdown to choose between one, two, or three content sections. Image Quality: You can place digital photos or logo art in your poster file by selecting the Insert, Picture command, or by using standard copy & paste. For best results, all graphic elements should be at least 150-200 pixels per inch in their final printed size. For instance, a 1600 x 1200 pixel photo will usually look fine up to 8“-10” wide on your printed poster. To preview the print quality of images, select a magnification of 100% when previewing your poster. This will give you a good idea of what it will look like in print.

A metadata schema is a common way of describing and organizing metadata. Metadata schemas are needed when working with more than one dataset, sharing information with other people, or searching across different systems using tools like APIs. MetaSat is a metadata schema written in JSON-LD that can be shared and expanded upon, and which will eventually facilitate information sharing between small satellite missions. The schema will be piloted by the Libre Space Foundation on their platform SatNOGS and incorporated into systems maintained by NASA’s Small Spacecraft Virtual Institute (S3VI). Ways to Contribute Shoot us an email: metasa[email protected] Use the Sorting Tool: metasat.schema.space Review the JSON-LD on Gitlab: gitlab.com/metasat JSON-LD Example "spacecraft" { "schema:name": "Lume 1", "dimensions": { "schema:height": { "schema:value": "10", "wdp:P6512": "CMT" }, "schema:width": { "schema:value": "10", "wdp:P6512": "CMT" }, "schema:height": { "schema:value": "22.70", "wdp:P6512": "CMT" }, } MetaSat aims to improve interoperability and access to mission outputs by removing ambiguity and providing the digital infrastructure necessary for crosswalking mission-related metadata and standards. MetaSat does not include mission data itself, but rather, data about mission data. In this way the schema remains a highly flexible tool regardless of its use case. Building Crosswalks Existing metadata can be “crosswalked” and linked to the MetaSat schema. The metadata crosswalk makes different standards translatable, while the schema itself makes it clear which standard is being used and in what context.
