Asset Metadata
what is asset metadata? asset metadata is static information that defines context or descriptive attributes of assets docid\ c4opdlucirj0draexrisp the term metadata is also used in asset properties docid\ cr6hbrdsl8fsuvlvm20if and measurements docid\ xqwlemdcnfff3 0h gmms it refers to the static nature of the information that is stored this way it allows you to say “this asset is located in hall b, packaging area ” “the maximum rated capacity of this mixer is 500 kg ” in other words, asset metadata is the set of descriptive fields that give some additional background to an asset, independent of live or historical measurements why does it matter? there is plenty of relevant information that does not come from a plc or a sensor, but instead derives from the specification of a machine, the physical environment where it is located in or in the mind of an operator asset metadata can be used to capture this information as well and use it effectively alongside time series data so in the end you can enrich your dataset, with relevant business and engineering information how does it fit in the system? each asset, regardless of its position in the asset tree, can have a set of metadata fields these fields consist of a name and a value the values you assign to metadata fields can be used in calculations docid\ opiodkgnngyjedx6zkg d , e g to calculate the tank volume based on a level measurement and the diameter specification of the tank in asset prototypes docid\ b7rjc9myvp lic5wbr yw , you can use asset metadata fields to determine the measurement names that should be linked to newly instantiated asset properties example for a mixer asset, metadata could include location → hall b capacity → 500 kg manufacturer → acme corp installationdate → 2022 03 14 when you use it you’ll work with asset metadata when you want to store static information about your assets docid\ c4opdlucirj0draexrisp configuring calculations docid\ opiodkgnngyjedx6zkg d that depend on certain attributes (e g engineering specifications) of an asset building asset prototypes docid\ b7rjc9myvp lic5wbr yw that can automatically link the correct measurements to the newly created asset properties common misconceptions asset metadata is not live data it doesn’t point to time series measurements or calculations that’s the role of asset properties docid\ cr6hbrdsl8fsuvlvm20if it is not automatically generated it must be defined explicitly for each asset best practices define a standard set of metadata fields per asset prototype (e g , location, engineering limit, manufacturer) when configuring asset properties on asset prototypes docid\ b7rjc9myvp lic5wbr yw , keep in mind that they are required fields when instatiating a new asset from a prototype keep (asset) metadata concise but meaningful avoid cluttering assets with unnecessary attributes avoid storing information that frequently changes in asset metadata this decreases the maintainability of your dataset more information standardizing metadata with asset prototypes docid\ b7rjc9myvp lic5wbr yw using metadata to reuse calculations docid\ vmelwzgf3ovtotokgj61q
