A physical/authentication element is present and specifies a method attribute with a value of MD5 or SHA-1
Check 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.
true
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.

Compare raw file size of file to [entity]/physical/size element in metadata. Return error if not matching.

Database table created
Status of creating a database table
A database table is expected to be generated from the EML attributes.
A database table was generated from the attributes description
Data are examined and possible record delimiters are displayed
If no record delimiter was specified, we assume that \r\n is the delimiter. Search the first row for other record delimiters and see if other delimiters are found.
No other potential record delimiters expected in the first row.
No other potential record delimiters were detected. A valid record delimiter was previously detected
Look 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 233101 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.

warn
A physical/authentication element is present and specifies a method attribute with a value of MD5 or SHA-1
Check 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.
true
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.

error
Compare the metadata checksum for an entity to the checksum of the downloaded entity
Two possible responses: valid if checksums match; error if checksums do not match.

Matching checksums will ensure data integrity during upload to the repository.
If the found integrity hash value does not match the expected integrity hash value, there may have been a loss of integrity in the data download. Check that the hash method and hash value documented in the metadata are the correct values.
