Biolinks connect bioitems in biologics objects. Their role is similar to bonds connecting atoms in structure ensembles.
Biolinks are minor objects. Their associated properties use a J_ prefix (mnemonical hint: these are bioitem joins).
biolink append bhandle label ?property value?...
j.append({?property:value,?...})
j.append(?property,value,?...)
Standard data manipulation command for appending property data. It is explained in more detail in the section about setting property data.
biolink defined bhandle label property
j.defined(property)
This command checks whether a property is defined for the biolink. This is explained in more detail in the section about property validity checking. Note that this is 
not
 a check for the presence of property data! The 
biologics valid 
command is used for this purpose.
biolink delete bhandle ?label?...
biolink delete bhandle all
j.delete()
Biolink.Delete(bref,?jlabel/jref/jrefsequence?,...)
Biolink.Delete(jref,...)
Biolink.Delete(bref,“all”)
Delete zero or more biolinks. The bioitems the links connect remain intact.
The special biolink label all requests deletion of all links.
The return value of the command is the number of deleted biolinks.
biolink delete $bhandle 1
This command is one of few biolink subcommands which do not require an biolink label. If no label is given, the command does nothing. This is useful for list expansions where the list might be empty:
eval biolink delete $bhandle $dellinklist
biolink delete $bhandle {*}$dellinklist
biolink dget bhandle label propertylist ?filterset? ?parameterdict?
j.dget(property=,?filters=?,?parameters=?)
Standard data manipulation command for reading object data. It is explained in more detail in the section about retrieving property data.
For examples, see the
 biolink get
 command. The difference between
 biolink get 
and 
biolink dget 
is that the latter does not attempt computation of property data, but rather initializes the property values to the default and return that default if the data is not yet available. For data already present, 
biolink get
 and 
biolink dget
 are equivalent.
biolink exists bhandle label ?filterlist?
b.exists(?filters=?)
Biolink.Exists(bref,label,?filters=?)
Check whether this biolink exists. Optionally, a filter list can be supplied to check for the presence of specific features. The command returns 0 if the biolink does not exist, or fails the filter, and 1 in case of successful testing.
biolink fill bhandle label ?property value?...
j.fill({property:value,...})
j.fill(?property,value?,...)
Standard data manipulation command for setting data, ignoring possible mismatches between the lengths of the lists of objects associated with the property and the value list. It is explained in more detail in the section about setting property data.
biolink filter bhandle label filterlist
j.filter(filters)
Check whether a biolink passes a filter list. The return value is boolean 1 for success and 0 for failure.
biolink get bhandle label propertylist ?filterset? ?parameterdict?
j.get(property=,?filters=?,?parameters=?)
j[property]
j.property
Standard data manipulation command for reading object data. It is explained in more detail in the section about retrieving property data.
For the use of the optional property parameter list argument, refer to the documentation of the 
ens get 
command.
Variants of the 
biolink get 
command are 
biolink new, biolink dget, biolink nget, biolink show, biolink sqldget
, 
biolink sqlget, biolink sqlnew 
and
 biolink sqlshow.
biolink index bhandle label
j.index()
Get the index of the bioitem. The index is the position in the biolink list of the biologics object. The first position is index 0.
biolink items bhandle label ?filterset? ?filtermode?
j.items(?filters=?,?mode=?)
Standard cross-referencing command to obtain the labels or references of the bioitems which are connected by the biolink. This is explained in more detail in the section about object cross-references.
biolink jget bhandle label propertylist ?filterset? ?parameterdict?
j.jget(property=,?filters=?,?parameters=?)
This is a variant of 
biolink get
 which returns the result data as a 
JSON
 formatted string instead of 
Tcl 
or
 Python 
interpreter objects.
biolink jnew bhandle label propertylist ?filterset? ?parameterdict?
j.jnew(property=,?filters=?,?parameters=?)
This is a variant of 
biolink new
 which returns the result data as a 
JSON
 formatted string instead of 
Tcl
 or
 Python 
interpreter objects.
biolink jshow bhandle label propertylist ?filterset? ?parameterdict?
j.jshow(property=,?filters=?,?parameters=?)
This is a variant of 
biolink show
 which returns the result data as a 
JSON
 formatted string instead of 
Tcl
 or
 Python 
interpreter objects.
biolink link bhandle label
Biolink.Ref(bref,identifier)
Return the biolink label stored in property J_LABEL ( Tcl ) , or a minor object reference ( Python ). This is useful in case the label used in the command is not a straightforward numerical label or reference but some other item identification format.
biolink new bhandle label propertylist ?filterset? ?parameterdict?
j.new(property=,?filters=?,?parameters=?)
Standard data manipulation command for reading object data. It is explained in more detail in the section about retrieving property data.
For examples, see the 
biolink get 
command. The difference between
 biolink get
 and 
biolink new 
is that the latter forces the re-computation of the property data, regardless whether it is present and valid, or not.
biolink nget ehandle label propertylist ?filterset? ?parameterdict?
j.nget(property=,?filters=?,?parameters=?)
Standard data manipulation command for reading object data. It is explained in more detail in the section about retrieving property data.
For examples, see the 
biolink get
 command. The difference between
 biolink get 
and 
biolink nget
 is that the latter always returns numeric data, even if symbolic names for the values are available.
Biolink.Ref(bref,identifier)
Python
 only method to get a biolink reference. See 
biolink link
 command.
biolink set bhandle label ?property value?...
j.set(?property,value?,...)
j.set({property:value,...})
j.property = value
j[property] = value
Standard data manipulation command. It is explained in more detail in the section about setting property data.
biolink show bhandle label propertylist ?filterset? ?parameterdict?
j.show(property=,?filters=?,?parameters=?)
Standard data manipulation command for reading object data. It is explained in more detail in the section about retrieving property data.
For examples, see the 
biolink get
 command. The difference between 
biolink get 
and 
biolink show 
is that the latter does not attempt computation of property data, but raises an error if the data is not present and valid. For data already present, 
biolink get
 and 
biolink show
 are equivalent.
biolink sqldget bhandle label propertylist ?filterset? ?parameterdict?
j.sqldget(property=,?filters=?,?parameters=?)
Standard data manipulation command for reading object data. It is explained in more detail in the section about retrieving property data.
For examples, see the 
biolink get 
command. The differences between 
biolink get 
and 
biolink sqldget 
are that the latter does not attempt computation of property data, but initializes the property value to the default and returns that default, if the data is not present and valid; and that the 
SQL
 command variant formats the data as 
SQL
 values rather than for 
Tcl
 or 
Python
 script processing.
biolink sqlget bhandle label propertylist ?filterset? ?parameterdict?
j.sqlget(property=,?filters=?,?parameters=?)
Standard data manipulation command for reading object data. It is explained in more detail in the section about retrieving property data.
For examples, see the 
biolink get 
command. The difference between

SQL
 values rather than for 
Tcl
 or 
Python
 script processing.
biolink sqlnew bhandle label propertylist ?filterset? ?parameterdict?
j.sqlnew(property=,?filters=?,?parameters=?)
Standard data manipulation command for reading object data. It is explained in more detail in the section about retrieving property data.
For examples, see the
 biolink get 
command. The differences between 
biolink get 
and 
biolink sqlnew 
are that the latter forces re-computation of the property data, and that the 
SQL
 command variant formats the data as 
SQL
 values rather than for 
Tcl
 or 
Python
 script processing.
biolink sqlshow bhandle label propertylist ?filterset? ?parameterdict?
j.sqlshow(property=,?filters=?,?parameters=?)
Standard data manipulation command for reading object data. It is explained in more detail in the section about retrieving property data.

command. The differences between 
biolink get
 and 
biolink sqlshow
 are that the latter does not attempt computation of property data, but raises an error if the data is not present and valid, and that the 
SQL
 command variant formats the data as 
SQL
 values rather than for 
Tcl
 or 
Python
 script processing.
