Type:metadata
System:knb
On failure:warn
Check for presence of an entity size elementLook for entity size element as a prep for checking congruence, and if not present, generate a warn. Note that to be most useful (i.e, to check congruence), entity size should contain the most precise measure of size, which is "byte" (the default unit); however, the presence or name of the entity size unit is NOT checked.Entity size is present. If unit="byte" or unit is omitted (default = byte), then congruence can be checked.Found entity size element with value of 882 and size unit specified as 'bytes'. Please note that a size element specified with a unit other than 'byte' will not be tested for congruence.Examining the entity size is prep for checking congruence. Including the element is best practice, and if not present, a warn is generated. To be most useful, entity size should contain the most precise measure of size, which is "byte" (the default unit).Include an entity size in bytes Example success: knb-lter-sbc.3.12. Example of size in units other than byte: knb-lter-mcr.6.56.

A physical/authentication element is present and specifies a method attribute with a value of MD5 or SHA-1Check for presence of a physical/authentication element containing a checksum or hash value for an integrity check (e.g. MD5, SHA-1). Warn if an entity does not have a physical/authentication element, or if none of the physical/authentication elements specify a method attribute with a value of MD5 or SHA-1.At least one physical/authentication element with a method attribute specifying MD5 or SHA-1 and containing a checksum or hash value that can be used to perform an integrity check on the data.No authentication element was found.PASTA will use this value to check the integrity of the data it downloads from your site. In addition, PASTA is planning to compare the contributor-supplied checksum/hash value documented in the physical/authentication element to the checksum/hash value of this entity downloaded from previous revisions of this data package. If PASTA already has a copy of this entity, it will be able to avoid an unnecessary download of the entity from your site, resulting in faster processing of the new data package revision when you update it in PASTA.Add a physical/authentication element and store the entity checksum or hash value in it using a method such as MD5 or SHA-1.
