Opf Files
About E-OPF Your agency HR office is required to establish and maintain electronic official personnel files (e-OPFs) for all employees. The e-OPF will be maintained and managed through SAP. Refer to Management Directive 505.18 for policy information. The OPF file, traditionally named content.opf, houses the EPUB book's metadata, file manifest, and linear reading order. This file has a root element package and four child elements: metadata, manifest, spine, and guide. Furthermore, the package node must have the unique-identifier attribute. The.opf file's mimetype is application/oebps.
It is the policy of the Department of General Services (DGS) that records of the Office of Human Resources (OHR) are open to public inspection at all times during normal working hours. Every person has the right to inspect any record except those that are exempted from public disclosure by statute or other authority.
Copies of records will be provided to any person with authorized access by OHR. The fee for this service may not exceed the direct cost of duplication. This includes the cost of operating the copy machine and the cost of the machine operator. Any reasonable portions of a record shall be provided after deletion of the portions that are exempted by law.
Records will not be removed from custody of the Personnel Officer or employee having responsibility for them. OHR reserves the right to be physically present during the inspection of any records.
Persons found guilty of stealing, willfully destroying, mutilating, defacing, altering or falsifying, removing or secreting, the whole or any part of such a record, map, book, paper or proceeding, or who permits any other person to do so, are punishable by imprisonment in state prison, or in a county jail not exceeding one year, or by a fine not exceeding $1000, or by both fine and imprisonment (Government Code [GC] section 6220-6201).
See “Public Record Inspection Guidelines” (GS 17) posted in the OHR reception area for further information.
DEFINITION
The term “personal information” means any information that is maintained by an agency that identifies or describes an individual, including, but not limited to, his/her name, social security number, physical description, home address, home telephone number, education, financial matters, and medical or employment history.
Personnel files contain employment records maintained by an employer for the purpose of administering benefits, providing training, and maintaining the employment history of employees for continued employment and/or promotional opportunities.
GC section 6254(c), Civil Code section 1798, and Penal Code section 832.7 an 502 protect the confidentiality of personnel records and strictly limit their disclosure. Locked files and appropriate physical safeguards shall be established by the Personnel Officer to ensure the security and confidentiality of personnel records.
OPF CONTENTS AND RETENTION
OPF material shall be maintained no longer than the period of time required by law and in accordance with the approved departmental retention period established for the record. The Official Personnel Folder Purging Chart provides guidance for items that may be in the employee’s OPF.

OPF is the open packaging format that is defined by idpf.
[edit]Overview
The Open Package format has a long history with the <idpf>. It is used in all three versions of the specification. It always contains the metadata that describes such things as the title, author name, etc. In Version 1 some use it as an alternate name for the standard which was officially called Open eBook. MOBI, LIT, and IMP all use a version 1 OPF (.opf) in their source.
All three versions have an entry called package which looks something like:
Version one does not contain the version number but version 2 and version 3 must be identified in the opening entry.
Edit Opf Files
Both Version 2 and version 3 use it as the internal file metadata used in ePub. In ePub 3 the OPF portion is now called the Publications standard. It is basically the same as OPF version 2.01 with a few additions.
[edit]Structure
The OPF file can be located anywhere in the ePub file structure and can be named whatever you wish. In ePub there is a folder called META-INF that must always be present. Inside there must be a file call container.xml. The content of that container file points to the OPF file. It might look like:
[edit]Specification
The Open Packaging Format (OPF) Specification, defines the mechanism by which the various components of an OPS publication are tied together and provides additional structure and semantics to the electronic publication.
Specifically, OPF:
- Describes and references all components of the electronic publication (e.g. markup files, images, navigation structures).
- Provides publication-level metadata. Specifically it should include Dublin Core formatted data with information about the eBook such as author and title.
- Provides a unique identification number. This is usually the ISBN if available.
- Specifies the linear reading-order of the publication.
- Provides fallback information to use when unsupported extensions to OPS are employed.
- Provides a mechanism to specify a declarative table of contents (the NCX).
- May provide pointers to additional optional elements such as embedded fonts.
Version 3 can contain version 2 data for backward compatibility but a version 3 reader will ignore all data not supported in version 3.
[edit]Example version 2
See ePub OPF section for one example. For an example of Version 1.2 see Open eBook Package File.Here is another 2.01 example:

[edit]Mobi specific
Mobi and the newer Kindle AZW and KF8 formats need special entries in the OPF for the TOC and Cover. You need to add the 'TOC' entry in the GUIDE section of the OPF in order for the TOC option to be made available.
The OPF file can be used to create an eBook using MobiPocket Creator or KindleGen simply by using it as the starting point for the compiler. It will find the other files necessary by parsing this file. Note the 'Start here' entry may also use type='text'
[edit]Unique id
The web site http://www.famkruithof.net/uuid/uuidgen can provide a unique id for an eBook as needed in the OPF.
